Question

total surface of cuboid is 22 m²,it's height is 1 m and breath 2m .find its length and volume
pls give step by step answer...and a correct answer...​

Answer 1

Answer:

length=6.7m

volume=13.4m^3

Step-by-step explanation:

let length = l

Given = b = 2m

h = 1m

T.S.A. of cuboid = 22m^2 - (given)

(lb+bh+hl) = 22m^2

(l×2+2×1+1×l) = 22m^2

(2l+2+1l) = 22m^2

3l+2. = 22m^2

3l. = 22 - 2

l = 20/3

l. = 6.7m

Volume of cuboid = l×b×h

= 6.7×2×1

= 13.4m^3

Answer 2

Answer:

3

Step-by-step explanation:

Tsa of a cuboid =2(lb+bh+hl)

22=2(lb+bh+hl)

11=2l+2+l

9=3l

l=3
