Sheet Lead Block
Find the dimensions of the square?
A block of lead is hammered out to form asquare sheet 10 mm thick. The original dimensions ofthe block were 1,6 dm x 0,7 dm x 0,2 dm. Find the dimensions of the square
The original block was 16 cm * 7 cm * 2 cm = 224 cubic cm.
10 mm thick = 1 cm thick.
So the surface of the square is 224 cubic cm / 1 cm = 224 square cm.
Take the square root of 224, and one side of the square is 14.967 cm. So the dimensions of the square are 14.967 cm x 14.967 cm.
