Question

Q6
Obtain the volume of rectangular boxes with the following lengths, breadth and
height respectively.
I) a,3b,7c​

Answer 1

Step-by-step explanation:

Solution:

We know that

Volume = length x breadth x height

(i) 5a x 3a² x 7a^4 = (5x 3x 7 ) x(a xa² xa^4 )

volume =105a^7

(ii) 2p x 4q x 8r = (2x 4x 8 )x ( px q x r)

volume = 64pqr

(iii) xy x 2x²y x 2xy² = (2x2 ) x (xy x²y xy²)

volume= 4x⁴y⁴

(iv) a x 2b x 3c = (2x 3) x ( a x b x c)

volume= 6abc
