Question
Obtain the volume of rectangular box with the length, breadth and height respectively: $5a, 3a^2, 7a^4$
✓
Answer
Volume of the rectangular box
= Length $\times$ Breadth $\times$ Height
$= (5a) \times (3a^2) \times (7a^4)$
$= (5 \times 3 \times 7) \times (a \times a^2 \times a^4)$
$= 105a^7$
= Length $\times$ Breadth $\times$ Height
$= (5a) \times (3a^2) \times (7a^4)$
$= (5 \times 3 \times 7) \times (a \times a^2 \times a^4)$
$= 105a^7$
