Question

5. A block of wood in the shape of a cuboid has length = 2.5 m,
breadth = 1.5 m and height = 2 m. How many cubical blocks,
each of edge 50 cm can be cut from it?​

Answer 1

Answer:

Answer. Volume of a cube of length a =50cm =50×50×50 cubic centimetre= 125×1000 cubic centimetre = 1.25×10^5 cubic centimetre . No. of blocks cut from the cuboid = 7.5×10^6/1.25×10^5 =60

Step-by-step explanation:

Answer 2

Answer:

Volume of bigger cuboid = l×b×h

= 2.5 × 1.5 × 2 = 7.5

Volume of smaller cube = 0.5 × 0.5 × 0.5(50 cm = 0.5 m) = 0.125

Let the no. of small cubes = n

Total volume of small cubes = n × 0.125

Now 7.5 = n × 0.125 ( conservation of volume)

n = 60
