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>
The angles of the triangle are given as to have measures of <span>45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:
c</span>² = a² + b²
c² = 2a²
4² = 2a²
a = 2√2
Hope this answers the question. Have a nice day.
