Question

A block of wood is 30 inches long, 6 inches wide, and 3 inches tall. It weighs 16.5 pounds. To the

nearest pound, what is its density in pounds per cubic inch?

Answer 1

The density of the block of wood is approximately 0.31 pounds per cubic inch (to the nearest pound).

Step-by-step explanation:

The density of an object is calculated by dividing its mass by its volume.

In this case, the block of wood weighs 16.5 pounds and has a volume of 6 in. x 3 in. x 3 in. = 54 in³.

Therefore, the density of the block of wood is 16.5 pounds / 54 in³ ≈ 0.31 pounds per cubic inch (to the nearest pound).
