What is the difference between the lateral area and surface area?

Lateral area is the area of the sides of a three-dimensional shape, excluding the base and top.

Surface area is the area of all of the sides of a shape.

For example, a the formula for the surface area of a cube is , where is the length of an edge of the cube. However, the formula for the lateral area of a cube is , where is also the length of an edge of the cube.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
