d= volume of the oil drop/ area of the film
= 4/3 *pi* (0.025cm)^3/(pi* (10 cm)^2
= 2.08X10^-7 cm
= 4/3 *pi* (0.025cm)^3/(pi* (10 cm)^2
= 2.08X10^-7 cm
Thank you so much
This answer is so useful
Thanks once again

So volume is required in both figures.
Volume of a cuboid L x B x H
L =36 cm, B= 25cm , H = 18 cm
Volume of cuboid =
36*25*18cm^3(Substituting the values)
Volume of a cube L^3
Edge ( length ) = 4cm
= 3*3*3cm^3
To find the number of cubes = Volume of a cuboid ÷ Volume of a cube
= (36*25*18) ÷ (3*3*3)
= 600 cubes
Ans : 600 cubes can be made.
