Find the volume, the total surface area and the lateral surface area of a cuboid which is 15 m long, 12 m wide and 4.5 m high |
|
Answer» Here, l = 15 m , b = 12 m and h = 4.5 m Volume of the cuboid `= (l xx b xx h)` cubic units `= (15 xx 12 xx 4.5) m^(3) = 810 m^(3)` Total surface area of the cuboid `= 2(lb + bh + lh)` sq units `= 2 (15 xx 12 + 12 xx 4.5 + 15 xx 4.5) m^(2) = 603 m^(2)` Lateral surface area of the cuboid `= [2 (l + b) xx h]` sq units `= [2(15 + 12) xx 4.5]m^(2) = 243 m^(2)` |
