The two right triangular prisms are similar solids.
Zanzabum

Answer:

<h2>The volume of the larger prims is eight times greater than the smaller prism.</h2>

Step-by-step explanation:

If the scale factor of the larger prims to the smaller prism is 3, that means each side is triple.

We know the a triangular prims has a volume defined by

V_{small} =\frac{b \times h_{1} }{2} \times h_{2}

If we take that formula as the smaller prism, then the larer prism has a volum of

V_{large} =\frac{2b \times 2h_{1} }{2} \times 2h_{2}=8(\frac{b \times h_{1} \times h_{2}  }{2} )

If we compare, we can deduct that

V_{large}=8V_{small}

In words, the volume of the larger prims is eight times greater than the smaller prism.
