Question

Fill in the blanks in each of the following so as to make the statement true:
(i) 1 $m^3$ = ___ $c{m}^3$
(ii) 1 litre = ___ cubic decimetre
(iii) 1 kl = ___ $m^3$
(iv) The volume of a cube of side 8 cm is ___.
(v) The volume of wooden cubiod of length cm and breadth 8 cm = is 4000 $c{m}^3$. The height the cubiod is ___ cm
(vi) 1 cu. dm = ___ cu.mm
(vii) 1 cu km = ___ cu.m
(viii) 1 litre = ___ cu.cm
(ix) 1 ml = ___ cu.cm
(x) 1 kl = ___ cu.dm = ___cu.cm

Answer 1

(i) 1 $m^3$ = 1000000 or ${10}^{6}c{m}^3$
(ii) 1 litre = 1 cubic decimetre
(iii) 1 kl = 1 $m^3$
(iv) The volume of a cube of side 8 cm is 512 $c{m}^3(V=a^3=8\times 8\times 8=512c{m}^3)$
(v) The volume of a wooden cuboid of length 10 cm and breadth 8 cm is 4000 $c{m}^3$. The height of the cubiod is 50 cm
$(Height=\frac{Volume}{l\times b}=\frac{4000}{10\times 8}=50cm)$
(vi) 1 cu.dm = 1000000 cu mm = ${10}^{6}cu.mm$
(vii) 1 cu.km = $1000\times 1000\times 1000cu.m={10}^{9}cu.m$
(viii) 1 litre = 1000 cu.dm = $100\times 100\times 100cu.cm={10}^{6}cu.cm$
