A gallon of paint will cover approximately 450 square feet. an artist wants to paint all the outside surfaces of a cube measuring 12 feet on each edge. what is the least number of gallons of paint he must buy to paint the cube
Accepted Solution
A:
To find the amount of paint needed, we need to find the total surface area.
A cube has 6 surfaces.
1 surface = 12 x 12 = 144 ft²
6 surfaces = 144 x 6 = 864 ft²
Find the number of gallons of paint needed:
864 ÷ 450 = 1.92 gallons of paint
