Figure out how many square inches on the cube. One side is 10" x 10" = 100 inches square.
6 sides makes 600 inches square.
A square foot is 12 x 12 inches = 144 inches square
Square footage is 600 / 144 = 4.17

1. 4.17 sq ft
a cube has 6 sides. Each side is 10in by 10in. to have your answer in sq ft we first convert inches to feet by dividing by 12. (12 inches per foot). 10/12 = .8333333 . Each side is .833333 X .833333 sq ft. or .6944444 sq ft. Multiply this by the six sides of a cube
6 X .694444 = 4.166667 or 4.17
Hope this helps

To cover cube you cover all 6 faces. Each face has area 100 square inches, so you need 600 Sq inches of paper. But I sq foot is 12 inches * 12 inches = 144 square inches, so you need 600/144 square feet of paper = 4.17

Take it stepwise:
Visualize a cube.
It has six sides.
Each side is 10in x 10in...ie 100 sq in.
6 sides x 100 sq in/side = 600 sq in.
A square foot is 12in x 12in...ie 144 sq in.
600 sq in / 144 sq in per sq ft = 4.17 sq ft (answer)

4.17
12 inches = 1 foot
144 square inches = 1 square foot
total area required to cover the cube = 6 * 10^2 square inches = 600 square inches.
Hence, 600 square inches = 600/144 square feet. = 4.166666 sq feet.

10 in x 10 in = 100 sq in per side.
there are 6 sides per cube so 100 sq in x 6 = 600 sq in.
600 sq in @ 144 sq in per sq ft = 600 / 144 = 4.17 sq ft

(10)(10)*6 = 600 square inches
area of square multiplied by the number of sides
convert inches to feet (12 inches = foot, 144 square inches = 1 square foot)
(600 square inches)(1 square foot/144square inches) = 4.17 square feet
the answer is
4.17 sq feet

with side of 10", each side is 100 in^2. That's 600 square inches. Divide by 144 (= 1 square foot) and you have 4.166666(repeating) square feet.

A=6*s^2=6*10^2=600 in^2
600in^2=600/144 ft^2=4.17ft^2
1st answer is correct

For a cube you have six faces 10" x 10" or 100 sq.in. per face,
so you need 6 faces X 100 sq.in. per face = 600 sq.in.
to find the area in sq. ft. divide the 600 sq.in. by 144 sq. in. per sq. ft. = 4.17 sq.ft.
