Question

Which sand-castle spire has a greater volume? How much more sand do you need to make the spire with the greater volume?

Answer 1

Answer: spire b has the greatest volume with a volume of 64. spire a has a volume of 60. you'll need 4 in^3 more sand.

Explanation:

since we know the volume of spire a is 60 while spire b’s volume is 64, from there, all you do is subtract 64 from 60. that gives us 4. meaning you need 4 in^3 more sand.
