Answer:
(a) l = 8 cm, b = 3 cm, h = 2 cm The volume of cuboid \[=\text{ l}\times b\times h\] \[=8\times 3\times 2\] The volume of cuboid \[=\text{ }48\text{ }c{{m}^{3}}\] (b) Height = 3 cm = 0.03 m Area of rectangle part \[=\text{ }24\text{ }{{m}^{2}}~~\] The volume of cuboid = Area of rectangle part \[\times \] Height \[=24{{m}^{2}}\times 0.03\,m\] The volume of cuboid \[=0.72\text{ }{{m}^{3}}\]
