Hi All,
The 'math' behind this question can be done in a variety of ways. Here's another way to perform the necessary calculation that keeps the numbers 'small':
We're told that each face of a cube is 10ft x 10ft = 100 sq. ft.
Since 1 quart of paint costs $3.20 and covers 20 sq. ft., we know that 5($3.20) = 5(20 sq. ft)...
5($3.20) = $16 of paint will cover 100 sq. ft.
Since a cube has 6 faces, we'll need to spend 6($16) = $96 to paint all of its sides.
Final Answer:
GMAT assassins aren't born, they're made,
Rich
