Asculpture is formed from a cylinder resting on top of a cuboid. the cylinder has a radius 40cm and height 70cm. the cuboid measures 80cm by 80cm by 140cm . the sculpture is made from steel , the steel has a density of 8.05g/cm*3 . calculate the total mass of the sculpture in tonnes. show all working (hurry need to submit assignment asap)

 Total mass of the sculpture is 11.07 tons .

Step-by-step explanation:

Formula

Where r is the radius and h is the height .

Volume of a cuboid = Length × Breadth × Height

As given

A sculpture is formed from a cylinder resting on top of a cuboid.

The cylinder has a radius 40cm and height 70cm. the cuboid measures 80cm by 80cm by 140cm .

Total volume =  Volume of a cylinder + Volume of a cuboid

Total volume = 351680 + 896000

                      = 1247680 cm³

Formula

As given

The sculpture is made from steel , the steel has a density of 8.05g /cm³ .

Mass = 8.05 × 1247680

           = 10043824 g

As 1 tons = 907185 grams

Convert 10043824g into tons .

                                     = 11.07 tons

Therefore the  total mass of the sculpture is 11.07 tons .
