How many square feet needed to make a box 4 feet by 3 feet by 6 feet?

Answer 1

The box has:

-- 2 sides that measure 4-ft by 3-ft

-- 2 sides that measure 4-ft by 6-ft

-- 2 sides that measure 3-ft by 6-ft

Each of the first pair has 12 square feet of area.

Each of the second pair has 24 square feet of area.

Each of the third pair has 18 square feet of area.

Total = (2 x 12) + (2 x 24) + (2 x 18) = 2 x (12 + 24 + 18) = 2 x (54) = 108 square feet.
