Oh lord help q-q
I have like no time left-

(Triangular pyramid)

Lateral area = 1650

Total surface area = 1860.1

(Triangular prism)

Volume = 660

Step-by-step explanation:

For the triangular pyramid

Area of triangle = × base × height

Area of the base = × 22 × 19.1 = 210.1

Area of the sides = × 22 × 50 = 550

Number of sides (excluding base) = 3

∴ Total Area = 210.1 + (550 × 3)

= 210.1 + 1650 = 1860.1

Lateral Area = (550 × 3)  = 1650

For the triangular prism

Area of the triangle = × 12 × 5 = 30

Volume = Area x Height

Volume = 30 ×  22 = 660

it's both, now can you answer my most recent question?

b, i believe, but not sure.
