Answer: 12 inches
Step-by-step explanation:
We know that the volume of a rectangular prism is given by :-
\(\text{Volume}=\text{Base area* height}\)
Given : A toy chest in the shape of a rectangular prism has a volume of 8,640 cubic inches.
The base area of the toy chest is 720 square inches.
Let h be the height of the toy chest, then we have
\(8640=720\times h\\\\\Rightarrow\ h=\dfrac{8640}{720}=12\)
Hence, the height of the toy chest = 12 inches
