Question

Alice is covering a foam cube with fabric to make a footstool. Each side of the cube is 20 inches. How many square inches of fabric will she need?
1. 120in.2
2.720in.2
3.1,200in.2
4.2,400in2

Answer 1

one side of cube= 20 inch
area of side of cube= side ×side
=20×20
=400
total side of cube =6
area of 6 side= 400×6
=2400sq.inch

Answer 2

Answer:

$2400 inches^2$

Step-by-step explanation:

We are given that Alice is covering a foam cube with fabric to make a footstool. Each side of the cube is 20 inches.

So, area of cube = $6x^{2}$

Where x is the side of cube

So, area of footstool = $6(20)^{2}$

                                  = $6\times 400$

                                  = $2400 inches^2$

Hence she need 2400 square inches of fabric
