volume of rectangular box=l×b×h
l=5a
b=3aa
h=7aaaa
volume=5a×3aa×7aaaa
=105a to the power of 7 cubic unit

Answer 2

Volume of rectangle = length x  breadth x  height. To evaluate volume of rectangular boxes, multiply all the monomials.

$(i)5a \times {3a}^{2} \times {7 a}^{2} = (5 \times 3 \times 7)(a \times {a}^{2} \times {a}^{4}) = {105a}^{7}$
