Question

Unit 5. 6) Please help. A block of wood has a density of 2.7 grams per cubic centimeter. If the block has a mass of 54 grams, what is its volume?

Answer 1

The correct answer is option 2, 20cm.

Answer 2

V = 20 cm^3

Explanation:

density = mass / volume

2.7 grams/ cm^3 = 54 grams / V

Multiply V on each side

V *2.7 grams/ cm^3 = 54 grams / V *V

Divide each side by 2.7

V = 54 grams / 2.7

V = 20 cm^3
