From the attachment, we have the following parameters





Solving further, we have:








From the calculations;

<em>This means that: QRS is isosceles</em>
<u>Given</u>:
Given that the figure is a triangular prism.
The length of the prism is 4 m.
The base of the triangle is 2.5 m.
The height of the triangle is 2.25 m.
We need to determine the volume of the triangular prism.
<u>Volume of the triangular prism:</u>
The volume of the triangular prism can be determined using the formula,

where b is the base of the triangle,
h is the height of the triangle and
l is the length of the prism.
Substituting b = 2.5, h = 2.25 and l = 4 in the above formula, we get;



Thus, the volume of the triangular prism is 11.25 m³
The answer to this is 30.41 due to the zero the answer cannot be moved on so it will stay the same.
