Simon calculated the volume of the prism. His work is shown here.

area of base = B = 1
2
bh = 1

(5)(13) = 32.5 m2

volume = Bh = 32.5(12) = 390 m3

A triangular prism. The triangular base has a base of 5 meters and height of 12 meters. The height is 4 meters.

What errors did he make? Check all that apply.
The area of the base is 30 m2, not 32.5 m2.
The area of the base is 60 m2, not 32.5 m2.
The area of the base is 78 m2, not 32.5 m2.
The volume of the prism is 108 m3, not 390 m3.
The volume of the prism is 120 m3, not 390 m3.

Options (1) and (5) are the correct options.

Step-by-step explanation:

See attachment for the complete question.

Simon's work,

Area of the base = B ==32.5 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 =

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.

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 =

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.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
