Question

1 m³of ice weighs 900kg.what is the weight of a cubical block of ice of side 0.5 m

Answer 1

Weight of 1 m^3 of ice = 900 kg

Length of edge of cubical block of ice = 0.5 m

We know that volume of cube is the result we get after we raise the length of edge of cube to three so,

Volume of cubical block of ice = ( Edge of cubical block ) ^ 3
V = ( 0.5 ) ^ 3
V = 0.125 m ^ 3
Volume of cubical block of ice = 0.125 m ^ 3

Since,

1 m^3 of ice weighs 900 kg.

Therefore,

0.125 m ^ 3 of ice will weigh ( 900 * 0.125 ) kg

0.125 m ^ 3 of ice will weigh ( 9 * 1.25 ) kg

0.125 m ^ 3 of ice will weigh 11.25 kg.

Hence,

Weight of cubical block of ice = 11.25 kg

Answer 2

Answer:

1 m^3 =900 kg

0.5 m^3=0.5 *900

0.125m=0.125*900

Answer is 112.5kg
