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

The area of the sheet of metal = 4.255 m²

The volume of the sheet of metal = 0.08553 m³

Explanation:

The area of a rectangle is given by the following relation;

Area, A = Length × Breadth

Therefore, the area of the rectangular sheet of metal, A, is given as follows;

A  = 4.234 m × 1.005 m = 4.255 m²

The area of the sheet of metal = 4.255 m²

The volume of the metal sheet id given by the relation, volume V= area × Thickness

The thickness of the sheet of metal = 2.01 cm = 0.0201 m

Therefore,

V = 4.255 m × 0.0201 m = 0.08553 m³

The volume of the sheet of metal = 0.08553 m³.

the answer is c. the lower legs are levers, and the knees are fulcrums. the ankles hold the loads.
