Question

find the height and total surface area of 6m long 5m broad and whose volume is 180m³​

Answer 1

Answer:

Answer

We are given l=8m,b=5m,h=3.5m. We know that

L.S.A. =2h(l+b)=2×3.5(8+6)=7×14=98m

2

Similarly,

T.S.A. =2(lb+bh+lh)=2(8×6+6×3.5+8×3.5)=2(48+21+28)=2×(97)=194m

Answer 2

For the volume of a cuboid it is given..

1.Length= 6m

2.Breadth=5m

3.Height= x (let's assume)

4.Volume= 180³

Volume=L×B×H

180=6×5×x

180=30x

180/30=x

6=x

Height=6m

_____________________________________________

For Total surface area(TSA) we have:

L= 6m

B= 5m

H= 6m

TSA= 2(lb+bh+hl)

2[(6×5)+(5×6)+(6×6)]

2[39+30+36]

2×105

210m²

Hope it helps!

Thanks!
