Question

Use the formula S A = 6s2 , where S A is the surface and s is the edge length of the cube , to solve his problem.


Gavan must paint a cube-shaped box. The edge length of the box is 2 1/2 feet. What is the surface area of the box?

Answer 1

To find the surface area of the cube using the formula, you would substitute in 2 1/2 for the length of the side.

SA = 6 x 2.5 x 2.5
SA = 37.5 ft.²

You are finding the area of one face (2.5 x 2.5) and multiplying it by six because there are six groups of this.

Answer 2

The surface area of the box will be 37.5 ft². For a particular figure, its surface area is different.

How to find the surface area of some object?

The area that its outer surfaces possess is called as the surface area. The sum of all those surfaces' area is the surface area of the considered object.

The given data in the problem is;

The surface area is,SA= 6s²

s is the edge length of the box = 2 1/2 feet.

The surface area is found as;

$\rm SA = 6a^2 \\\\ \rm SA = 6(2.5)^2 \\\\ SA=37.5 \ ft^2$

Hence, the surface area of the box will be 37.5 ft².
