Question

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

Answer 1

Answer:

significant figure is upto 1 decimal place

Answer 2

Answer:

area = 8.7209478m²

volume = 0.085528917m³

Explanation:

length of rectangular sheet = 4.234m =

423.4cm

breadth of rectangular sheet = 1.005m =

= 100.5cm

thickness of rectangular sheet = 2.01cm

so,,

area of rectangular sheet = 2(lb+bh+lh)

= 2(423.4×100.5+100.5×2.01+2.01×423.4)

= 2(42551.7+202.005+851.034)

= 2(43604.739)

= 87209.478cm² ..... ans.

= 8.7209478m² .....ans.

volume of rectangular sheet = lbh

= 423.4×100.5×2.01

= 85528.917cm³ ....ans.

= 0.085528917m³ ....ans.
