Question

Help me with this cube surface area.

Answer 1

Answer: 8 square foot

Explanation:

`A = 6a^(2),`

Convert: 1 ft = 12 in

Divide: 12in / 3 = 4 in

1 / 3 ft = 4 in

L X W = 4in X 4in = area on one side 16 in

Surface Area = 16in x 6 sides = 96 sq in

Convert to Sq Inches to Sq Foot

96 / 12 = 8 square foot

Answer 2

Explanation:

`a = 6 {x}^(2)`

Since the figure shows 1/3

`a = (6) { (1)/(3) }^(2)`

Squaring fractions is pretty much squaring the numerator and denominator. 1 squared is 1. 3 squared is 9, so....

`a = (6) (1)/(9)`

`a = (2)/(3)`
