Options (1) and (5) are the correct options.
Step-by-step explanation:
The given question is incomplete: find the complete question attached.
Simon's work,
Area of the base = B =
=
m²
Volume = Bh = 32.5(12) = 390 m³
Let's check the error's he made.
Area of the base of the triangular prism
B =![\frac{1}{2}bh=\frac{1}{2}(5)(12)](/tpl/images/0641/9632/fe2b3.png)
B = 30 m²
Volume of the prism = (Area of the triangular base)×(Height)
V = 30 × 4
V = 120 m³
Therefore, Options (1) and (5) are the correct options.
