Question

Five equal cubes, each of edge 5 cm, are placed adjacent to each other. The volume of the cuboid so formed, is

(a) $125c{m}^3$

(b) $375c{m}^3$

(c) $525c{m}^3$

(d) $625c{m}^3$

Answer 1

Each edge of 5 cubes =5 cm
$\therefore$ Placing than adjacent to each other,

Length of new cuboid (l)

$=5\times 5=25cm$

Breadth (b)=5 cm

and height (h)=5 cm

$\therefore$ Volume of new cuboid =lbh

$=25\times 5\times 5c{m}^3=625c{m}^3$
