length of square prism (l)= 10cm
breadth of square prism(b) = 10cm
height of square prism (h)= 20cm
(a): volume of square prism
= l × b × h
= 10 × 10 × 20
= 2000 cm^3
(b): (see the figures )
r = 5cm
h =20cm
volume of the largest cylinders that can be
carved out from the above square prism
(see fig 1.2 (b)
= πr^2h
= 3.14 × 5 × 5 × 20
= 1570 cm^3
