If Elena uses the off of her sand, she will need 5 containers
Volume is a measure of occupied three-dimensional space. It can be measure on cubic of any units
The formula for calculating the volume of a prism is expressed as:
V = lwh
where
l is the length
w is the width
h is the height
Determine the volume
Volume =. 5cm * 10cm * 4cm
Volume = 200cm^3
Since Elena has 1000cm^3 of sand, the total container that she needs is expressed as:
Total sand = 1000/200
Total container = 5 containers
Hence if Elena uses the off of her sand, she will need 5 containers
