An action hero needs to replace a valuable artifact with a pile of sand of equal mass within 5 seconds, otherwise a trapdoor opens and she falls into a pit of slimy slugs. The artifact and two of its measurements are shown in the following image

dimensions of said image below-

The picture is of an easter island statue

9.5 cm width
38.1 height

She assumes the artifact is made of limestone, which has a density of 2.71 g/cm^3. She plans to quickly replace the artifact with a pile of sand of equal mass. Sand has a density of 1.6 g/cm^3.

What common three-dimensional figure best models the artifact?

I would say rectangular prism?

B. To the nearest tenth of a cm^3, what is the volume of the three-dimensional figure you chose?

Use your answer to part B and the formula density= mass/volume to estimate the mass of the artifact

Estimate the volume of the sand she should use to replace the artifact
