Question

Find the voulme of a cuboid whose
(i) length = 12 cm, breadth = 8 cm, height = 6 cm
(ii) length = 1.2 m, breadth = 30 cm, height = 15 cm
(iii) length = 15 cm, breadth = 2.5 dm, height = 8 cm.

Answer 1

In a cuboid,
(i) Lenght (l) = 12 cm
Breadth (b) = 8 cm
Height (h) = 6 cm
$\therefore Volume=lbh=12\times 8\times 6c{m}^3=576c{m}^3$
(ii) Length (l)= 1.2 m = 120 cm
breadth (b) = 30 cm
Height (h)= 15 cm
$\therefore Volume=lbh=120\times 30\times 15c{m}^3$
= $54000c{m}^3$
(iii) Length (l)= 15 cm
breadth (b) = 2.5dm = 25 cm
Height (h)= 8 cm
$\therefore Volume=lbh$
= $15\times 25\times 8c{m}^3=3000c{m}^2$
