A toy pyramid (not shown) is made from poly(methyl methacrylate), better known by its trade term Lucite. The toy pyramid has a regular hexagonal base of `15 cm^(2)` and a height of 4 cm. In the base of the pyramid, there is a semispherical indentation 2 cm in diameter. If the pyramid weighs 21.129 g, then what is the density of Lucite? (Density equals mass divided by volume).

A

`1.06g//cm^3`

B

`1.18g//cm^3`

C

`2.09g//cm^3`

D

`6.51g//cm^3`
