Question

ble 1. Find the volume, the total surface area and the lateral surface area of a cuboid which
XAMPLES
is 12 m long, 8 m broad and 4.5 m high.​

Answer 1

Answer:

1.total surface area of cuboid =2(lb +bh+lh)=2(12×8+8×4.5+12×4.5)=2(96+36+54)=

2(186)=372sq.m

2.lateral surface area=2h(l+b)=2×4.5(12+8)=9(20)=180sq.m

3. volume =lbh=12×8×4.5=432cubic.m
