Final answer:
The value of height 'h' in the formula v = lwh where l = 5, w = 6, and v = 90, is 3 units.
Step-by-step explanation:
The student is trying to find the value of h in the formula v = lwh where v is the volume, l is the length, w is the width, and h is the height. We are given the values of l = 5, w = 6, and v = 90. To find h, we rearrange the formula to solve for h:
h = v / (lw)
Plugging in the given values yields:
h = 90 / (5 × 6)
h = 90 / 30
h = 3
So, the value of height h is 3 units.
