Answer 1

Answer:10

Step-by-step explanation:

Let the height be h.

A.T.Q.

540=2(15+12)*h

270=27*h

h=10 (value so provided)

Answer 2

Answer:

Step-by-step explanation:

Area of four walls=lateral surface area=2h(l+b)

l=15m

b=12m

So 2h(l+b)= 2h(15+12)

or, 540=2h*27

or, 2h=540/27

or, 2h=20

or, h=20/2

or, h=10m (Ans)
