Solving Word Problems Involving Volume of Cubes :
Here we are going to see some practice questions solving mensuration word problems with the shape cubes.
Question 1 :
Find the volume of a cube each of whose side is (i) 5 cm (ii) 3.5 m (iii) 21 cm
(i) 5 cm
Volume of cube = a3
Volume of cube = 125 cm3
(ii) 3.5 m
Volume of cube = 42.875 cm3
(iii) 21 cm
Volume of cube = 9261 cm3
Question 2 :
A cubical milk tank can hold 125000 litres of milk. Find the length of its side in metres.
Volume of cubical milk tank = 125000 liters
1 m3 = 1000 liter
Volume of tank in m3 = 125000/1000
a3 = 125
a = 5 m
Question 3 :
A metallic cube with side 15 cm is melted and formed into a cuboid. If the length and height of the cuboid is 25 cm and 9 cm respectively then find the breadth of the cuboid.
Volume of cube = Volume of cuboid
a3 = 153
Volume of cube = 3375
length x breadth x height = 3375
25 x breadth x 9 = 3375
breadth = 3375/(25 x 9)
= 15 m
