{Hint: Volume of a rectangular prism = length$\times$ width$\times$ height}

• A. 8 in
• B. 12 in
• C. 15 in
• D. 10 in

Answer 1

The correct option is D 10 in

Length of the aquarium = 15 in
Width of the aquarium = 12 in
Height of the aquarium = ?
Volume of the aquarium = volume of water it can hold
= length$\times$ width $\times$height
= 1800 cu in
15 $\times$ 12 $\times$ height = 1800
180 $\times$ height = 1800
Height = 1800 $÷$ 180
Height = 10 in
