12 pints of paint Margaret needs to buy in order to paint 3 boxes. So, option C is the correct answer.
What is the volume of the cuboid?
The volume of the cuboid is the product of the length, breadth, and height of the given prism.
Volume of cuboid = (length x width x height)
Margaret is building storage boxes. Each box will have a length of 8 feet, a width of 5 1/2 feet, and a height of 4 1/2 feet.
A pint of paint covers 50 square feet.
Volume of cuboid = (length x width x height)
= 8 (4.5)(5.5)
= 198
pints of paint Margaret needs to buy to paint 3 boxes
198 (3) = 594 square feet
50 square feet = 1 pints
1 square feet = 1/50 pints
594 square feet= 594/50
= 11.88
Thus, 12 pints of paint Margaret needs to buy to paint 3 boxes.
