The length, breadth and thickness of a rectangular sheet of metal are 4.234 m, 1.005 m, and 2.01 cm respectively. Give the area and volume of the sheet to correct significant figures.

Answer:

We know that, area of the rectangle = length x breadth

= 4.234 x 1.005 = 4.255 m²

Area of the rectangle = 4.3 m²

Expression of the volume of the rectangle = length x breadth x thickness

= 4.234 x 1.005  x  2.01 x 10^-2 

Volume of the rectangle = 8.55 x 10^-2 m³.
