What is the density of the board?

Enter your answer as decimal in the box. Round only your final answer to the nearest tenth.

Answer 1

Density = Mass/Volume
D = M/V
D = 0.07/0.063
D = 1.111111111111111
 
Volume of a rectangular prism is WHL
Volume of a rectangular prism is 0.3 m * 2.1 m * 0.1 m
Volume of a rectangular prism is 0.063
