Answer:
fish tank is 14.87 ≈ 15 inches tall.
Step-by-step explanation:
Given : A rectangular fish tank contains 3,240 cubic inches of water. The dimensions of the base of the fish tank are 12 inches x 18 inches.
To find : How tall is the fish tank.
Solution : We have given that volume of fish tank = 3240 cubic inches.
Length of tank = 12 inches.
Width of tank = 18 inches .
Volume of rectangular tank = length * width * height
3240 = 12 * 18* height .
3240 = 216 * height.
On dividing both side by 216 and switching the sides .
Height = [tex]\frac{3240}{216}[/tex] .
Height = 14.87 inches
Therefore, fish tank is 14.87 ≈ 15 inches tall.
