Question

What is the total cost of oil in a cubical container of side 2 m if it is measured and sold using a cubical vessel of height 10 cm and the cost is ` 50 per measure?

Answer 1

vol container=2^3=8
vol vessel=10^3=1000
rate=50/1000
Cost=8×50/1000=0.4

Answer 2

Side of the cubical container = 2m

Height of the cubical vessel = 10cm

We know that,

1m=100cm

Therefore, side of the cubical container = 200cm

Volume of oil in the cubical container = (200)^3

Volume of oil in one vessel = (10)^3

Therefore,

Number of vessels = (200)^3/(10)^3

=8000000/1000

=8000

Cost of 1 vessel = Rs. 50

Therefore, Cost of 8000 vessels = Rs.(8000 x 50)

=400000
