Answer:

7.809167 g/cm^3

Explanation:

Okay. First, find the volume of the the cuboid.

V = L x W x H

Both bases are squares. 6 x 6 = 36. 36 x 9 = 324.

The Volume of the cuboid is 324 cm^3.

The density of the cuboid is .68 g/cm^3.

Multiply these values. 324 x .68 = 220.32

The mass of the cuboid is 220.32 g.

Subtract this from the total mass. 970 - 220.32 = 749.68.

The pyramid has a mass of 749.68 g.

Find the volume of the pyramid. 17 - 9 = 8.

8 is the perpendicular height.

8 x 36 = 288

288 / 3 = 96

The Volume of the pyramid is 96 cm^3.

Divide the bolded values.

749.68 / 96 = 7.809167 g/cm^3
