A cylindrical road roller made of iron is 1.5 m wide its inner diameter is 60 cm and the thickness of iron sheet rolled into the road roller is 10 cm . find the weight of roller if 1 centimeter cube weight 8 gram.?
Answers
Answer:
weight of roller is 720 Kg
Step-by-step explanation:
Given
Width of roller = 1.5m = 150cm
diameter of roller = 60cm
thickness of sheet of roller = 10cm
if we unrolled the roller into sheet ,width of roller is the length of sheet AND diameter of roller is the breadth of the sheet
To find the Weight of roller so we have to find the volume of roller that is equal to the volume of sheet
Volume of sheet = L×B×H
=150×60×10
=90000 cube cm
Therefore the volume of roller is 90000 cube cm
if 1 cube centimetres =8 gm
then 90000 cube centimetres =8×90000
=720000 gm
=720 kg
Therefore, the weight of roller is 720 kg
the weight of the road roller is 720 kg
