# What is the surface area of a rectangle box?

## What is the surface area of a rectangle box?

The width, height, and length of a box can all be different. If they are the same, then the box will become a perfectly square box. The volume, or amount of space inside a box is h × W × L. The outside surface area of a box is 2(h × W) + 2(h × L) + 2(W × L)

What is the formula for total surface area?

Variables:

Surface Area Formula Surface Area Meaning
SA=4πr2 Find the area of the great circle and multiply it by 4.
SA=B+πrS Find the area of the base and add the product of the radius times the slant height times PI.

What is the surface area of a solid cube?

Explanation: The surface area of a cube = 6a2 where a is the length of the side of each edge of the cube. Put another way, since all sides of a cube are equal, a is just the lenght of one side of a cube.

### How do you find the surface area of a solid?

To determine the surface area of a solid, we take the sum of the area of all the surfaces of a 3-dimensional solid object.

Which of this formula is used to calculate the area of rectangle?

To find the area of a rectangle, we simply need to multiply its length by its width. The area is simply the width of a rectangle times height. Area = h × h, Area = h2. Hence for a square, the area is the square of its sides.

What is the total surface area of the prism?

The formula for the surface area of a prism is obtained by taking the sum of (twice the base area) and (the lateral surface area of the prism). The surface area of a prism is given as S = (2 × Base Area) + (Base perimeter × height) where “S” is the surface area of the prism.

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

A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

What is the name of the total area of the surface of a solid?

Surface Area. The total area of the exterior surface of a solid. Lateral Area.

What is formula of rectangular?

A = l × b. The area of any rectangle is calculated, once its length and width are known. By multiplying length and breadth, the rectangle’s area will obtain in a square-unit dimension. In the case of a square, the area will become side2.

## What is the total surface area of a triangular prism?

The formula used to calculate the surface area of a triangular prism is, Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh; where ‘b’ is the bottom edge of the base triangle, ‘h’ is the height of the base triangle, L is the length of the prism and S1, S2 and S3 are the …
