Question

How many square feet of paper do you need to cover a cube with a side 10 in. long? Round your answer to two decimal places.

Answer 1

$10 in = 0.83 ft= \frac{5}{6} ft\\ A=6* (\frac{5}{6}) ^{2}=4.17$

So the answer is A. 4.17 sq ft.

Answer 2

Answer: A. 4.17 sq ft

Step-by-step explanation:

The total surface area of cube is given by :_

$T.A.=6(side)^2$

Given: The side of cube = 10 in.

We know that 1 feet = 12 inch

∴$1\ in.=\frac{1}{12}\ ft$

Therefore, the  side of cube =$10\times\frac{1}{12}\ ft=\frac{10}{12}\ ft$

Then the  total surface area of cube is given by :_

$T.A.=6(\frac{10}{12})^2\\\\=6(\frac{100}{144})\\\\=4.16666666667\approx4.17\ sq\ ft$
