Question

A rectangular block of ice measures 42cm x 25cm x 18cm. Calculate its weight in kg if 1cm of cube of ice weigh 0.9g​

Answer 1

Step-by-step explanation:

for calculating weight we need volume of the rectangular block

.

if you mean that 0.9g = 1cm3

then its

.

Length of Ice block= 42 cm

Breadth of ice block= 25cm

Height of ice block=18cm

We know that volume=

Length× Breadth× Height42× 25× 18 =18900 cm3

Weight of 1cm3 of ice= 0.9g

Weight of 18900cm3 of ice= 18900×0.9 =17010g

17010/ 1000kg

= 17.01 kg
