Answer:
26.52 cubic inches
Step-by-step explanation:
We need to find the volume of each box and then multiply by 3.
The volume of a cylinder is given as:
where r = radius
h = height
The height of each box is 5 inches and its radius is 0.75 inches.
Therefore, the volume of each box is:
V = 8.84 cubic inches
The volume of 3 boxes will therefore be:
V = 8.84 * 3 = 26.52 cubic inches
26.52 cubic inches of material is needed to make 3 boxes.
