Answer:
The base and height of the solid is 5.5cm
<em></em>
Step-by-step explanation:
Given
Required
Determine the dimensions that maximizes the volume
Let the base dimension be x and the height be h
The volume is calculated as:
181.5 =x^2h
The surface area (S) is calculated as this:
Substitute 181.5 for S
Make h the subject:
Substitute in
To get the maximum, we differentiate V with respect to t and set the differentiation to 0
Set to 0
Multiply through by 4
Recall that:
So, we have:
<em>Hence, the base and height of the solid is 5.5cm</em>
