Question

A square brass plate of side x cm is 1 mm thick and weighs 5 44 kg
if 1 cm^3 of brass weighs 8 5 g , find the value of x

Riti Agarwal · Answer

Volume of square brass plate=1/10x^2 cm^3
ATP, 1cm^3=8 5g
Then, 1/10x^2 cm^3=8 5*1/10x^2
ATP, 8 5*1/10x^2=5440
or 1/10x^2=5440/8 5
or x^2=5440/8 5*10
or x^2=6400
or x=80cm

A square brass plate of side x cm is 1 mm thick and weighs 5.44 kg . if 1 cm^3 of brass weighs 8.5 g , find the value of x.
