Question:

Obtain the volume of rectangular boxes with following length, breadth and height given respectively: (i) 5a, 3a², 7a⁴ (ii) 2p, 4q, 8r (iii) xy, 2x²y, 2xy² (iv) a, 2b, 3c

Solution:

Volume=Length×Breadth×Height
V=l×b×h
(i)V=5a×3a²×7a⁴=105a⁷
(ii)V=2p×4q×8r=64pqr
(iii)V=xy×2x²y×2xy²=4x⁴y⁴
(iv)V=a×2b×3c=6abc
