Answer:

(Triangular pyramid)

Lateral area = 1650m^{2}

Total surface area = 1860.1m^{2}

(Triangular prism)

Volume = 660cm^{3}

Step-by-step explanation:

<u> For the triangular pyramid</u>

Area of triangle = \frac{1}{2} × base × height

Area of the base = \frac{1}{2} × 22 × 19.1 = 210.1

Area of the sides = \frac{1}{2} × 22 × 50 = 550

Number of sides (excluding base) = 3

∴ Total Area = 210.1 + (550 × 3)

= 210.1 + 1650 = 1860.1m^{2}

Lateral Area = (550 × 3)  = 1650m^{2}

<u>For the triangular prism</u>

Area of the triangle = \frac{1}{2} × 12 × 5 = 30

Volume = Area x Height

Volume = 30 ×  22 = 660cm^{3}
