What is the area formula for a box?

What is the area formula for a box?

(a) If l, w, and h are the length, width, and height of a box, its surface area is given by surface area = 2*(l*w + l*h + w*h).

What is the surface area of a square based box?

The surface area of a square based box is A=2×2+4xy, its volume is V=x2y, where x is length of the 4 sides of the base and y is the height.

How do you find the surface area of a container?

Use the formula SA=2 (ℓ× b + ℓ × h + b × h)

How do you find the dimension of a rectangular box?

Example: find the volume of a rectangular box For example, if the two sides of the base are of length 3 inches and 6 inches respectively, and the height of the box is 2 inches, then using the box volume equation results in 3 x 6 x 2 = 18 x 2 = 36 in3 (cubic inches).

What is the surface area of rectangle?

The area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h.

How do you find the surface area of one side of a rectangle?

In general, to find the surface area of a rectangular solid, remember that each face is a rectangle, so its area is the product of its length and its width (see the image below). Find the area of each face that you see and then multiply each area by two to account for the face on the opposite side.

How do you find the width and surface area of a rectangular prism?

The formula for volume of a rectangular prism is:

1. V=l×h×w , where V= Volume, l= length, h= height, and w= width.
2. 11,232=13×36×w.
3. 11,232=468×w.
4. Divide both sides by 468 .
5. 11,232468=w.
6. 24=w.
7. Hence, the width is 24 feet.

What is the formula for finding the area of a rectangle?

Explanation: To find the area of a rectangle, multiply its width by its height. If we know two sides of the rectangle that are different lengths, then we have both the height and the width.

How do I figure out area of a rectangle?

To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle.

What is the equation for finding surface area?

This sector’s area is given by the formula A = πrs, where s is the slant height of the cone (length from the cone’s point to base along the side). The equation for the surface area is therefore Surface Area = πr^2 + πrs.

What is the equation for the surface area of a rectangle?

Formula for area of a rectangle. The surface area of a rectangle can be found by the formula. Surface area of a Rectangle = L × B, where L is the length of the Rectangle and B is the breadth of the rectangle.

What are the steps of surface area?

Steps Know the parts of the equation, Surface Area = 4πr 2. Find the radius of the sphere. Square the radius by multiplying it by itself. Multiply this result by 4. Multiply the results by pi (π). Remember to add you units to the final answer. Practice with an example. Understand surface area.

How do you calculate lateral surface area?

The general formula for the lateral surface area of a regular pyramid is lateral area = (perimeter of base x slant height of pyramid) ÷ 2. Calculate the perimeter of the base by multiplying the length of one edge by four because a square has four equal sides.
