Question

Find the cost of wax used to make a cube of side 12 cm if the rate of the wax is ₹5 per cu.cm.​

Answer 1

Answer:

A cuboidal block is melted & recast into cubes.

So volume is required in both figures.

Volume of a cuboid L x B x H

L =36 cm, B= 32 cm , H = 0.25 m =0 .25 * 100 = 25cm

Volume of cuboid =

36*32*25 cm^3(Substituting the values)

Volume of a cube L^3

Edge ( length ) = 4cm

= 4*4*4 cm^3

To find the number of cubes = Volume of a cuboid ÷ Volume of a cube

= (36*32*25) ÷ (4*4*4)

= 450 cubes

Ans : 450 cubes can be made.

Answer 2

$6 \times 5 = 30rupees$
