Answer:
A) 843.75 ft³
B) 15.625ft³
C) 54 boxes
Step-by-step explanation:
A) To find the volume of a rectangular prism (the cargo hold is a rectangular prism), you multiply the length, the width and the depth:
Volume = length x width x depth
Volume = 15 x 7.5 x 7.5
Volume = 843.75 ft³ (ft³ or cubic feet is the unit for volume in feet)
B) The volume of a cube (the boxes are cube-shaped) is also found by multiplying the length, the width and the depth:
Volume = length x width x depth
Volume = 2.5 x 2.5 x 2.5
Volume = 15.625ft³
C) To find the amount of boxes that can fit, we see how many times the volume of one box goes into the volume of the cargo hold. Divide the volume of the cargo hold by the volume of the box:
843.75 ÷ 15.625 = 54
