Question

A sculptor has a copper piece in the shape of a rectangular prism. The piece measure 5 miles by 0.9 mile by 0.02 mile and its mass is 894 kilograms. What is the density of the copper? Enter your answer as a decimal in the box. Round only your final answer to the nearest tenth.

Answer 1

The answer to this question is 9933.3 Kg/mi.^3

Answer 2

Answer: The density of the copper is 9933.33 kg/miles³.

Explanation:

Since we have given that

Length of rectangular prism = 5 miles

Width of rectangular prism = 0.9 miles

Height of rectangular prism = 0.02 miles

So, volume of rectangular prism = length × breadth × height

So, it becomes,

`Volume=5* 0.9* 0.02\\\\Volume=0.09\ miles ^3`

As we know the relation between "Mass and density":

`Mass=Volume* Density\\\\Density=(Mass)/(Volume)\\\\Density=(894)/(0.09)\\\\Density=9933.33\ kg/miles^3`

Hence, the density of the copper is 9933.33 kg/miles³.
