Question

Which would take up more space, a pound of granite or a pound of basalt?

Answer 1

Since basalt is denser than graphite, a pound of basalt would take up less space

Answer 2

1 pound of granite

Explanation:

The density of granite is 168.6 lb/ft³. The volume occupied by 1 pound of granite is:

1 lb × (1 ft³/168.6 lb) = 0.00593 ft³

The density of basalt is 188 lb/ft³. The volume occupied by 1 pound of basalt is:

1 lb × (1 ft³/188 lb) = 0.00532 ft³

As we can see, 1 pound of granite takes up more space than 1 pound of basalt.
