An aquarium can be modeled as a right rectangular prism. Its dimensions are 14 in by 7 in by 4 in. If the aquarium contains 153

A right rectangular prism can be used to simulate an aquarium. Its measurements are 14 by 7 by 4 inches. If there are 153 cubic inches of water in the aquarium, There is a 61 % empty space.

<h3>What is volume?</h3>

The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.

The volume of the aquarium is;

V=14 × 7 × 4 = 392 inch³

The % by which the container is empty is found as;

$\%Empty= \frac{392-153}{392} \times 100 \ \\\\ \%Empty= \frac{239}{392} \times 100 \\\\ \%Empty= 61\%$
