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.
