Question

A sculpture is formed from a cylinder resting on a cuboid. The cylinder has radius 35cm and height 60cm. The cuboid measures 70cm by 70cm by 130cm. The sculpture is made of marble. The marble has a density of 2.7g/cm^3. Calculate the total mass of the sculpture in tonnes.

Answer 1

A sculpture is formed from a cylinder resting on top of a cuboid the cylinder has a radius of 40 cm and a height of 70cm. the cuboid measures 80cm by 80cm by 140cm. the sculpture is made of steel. the steel has a density of 8.05 g/cm^3 calculate the total mass of the sculpture in tonnes.

Answer 2

22565kg

Explanation:

total volume = 35 * 35 * pi * 60 + 70 * 70 * 130 = 867907cm^3

==> mass = 2.6 * 867907 = 2256558g = 22565kg
