Question:
Tick (✓) the correct answer:
Five equal cubes, each of edge 5 cm, are placed adjacent to each other. The volume of the cuboid so formed, is
(a) 125 cm3
(b) 375 cm3
(c) 525 cm3
(d) 625 cm3
Solution:
(d) $625 \mathrm{~cm}^{3}$
Length of the cuboid so formed $=25 \mathrm{~cm}$
Breadth of the cuboid $=5 \mathrm{~cm}$
Height of the cuboid $=5 \mathrm{~cm}$
$\therefore$ Volume of cuboid $=25 \times 5 \times 5=625 \mathrm{~cm}^{3}$
