Answer:
6.75 cubic metres
Step-by-step explanation:
Volume = lbh
Here there are 4 walls but they differ due to the horizontal lenth of the walls (3.5m and 4m).So,
V¹ = l¹bh
= (4*0.15*3) *2=3.6 cubic metres
V²= l²bh
=(3.5*0.15*3) *2= 3.15 cubic metres
V¹ + V² = 6.75 cubic metres
[I have multiplied with 2 because pair of walls have same length]
