Question

Surface area of this right prism

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}$

$\textsf{Let's calculate the surface area of given right prism}$

$\textbf{Area of Triangles :}$

• $\sf{\dfrac{1}{2}\cdot 16\cdot 12}$

• $\sf{8×12}$

• $\sf96 \: \: cm {}^{2}$

$\textsf{Since there are two triangles, }$

$\textsf{Area of Triangles = 96 × 2 = 192 cm²}$

$\textbf{Now, calculate the Areas of rectangles :}$

• $\textsf{Area - 1 = 12 × 10 = 120 cm²}$

• $\textsf{Area - 2 = 16 × 10 = 160 cm²}$

• $\textsf{Area - 3 = 20 × 10 = 200 cm²}$

$\textsf{Now add them all :}$

• $\textsf{120 + 160 + 200 + 192}$

• $\textsf{672 cm²}$

Answer 2

Answer:

Step-by-step explanation:

(16+12+20)*10+16*12= 48*10+192+480+192=672 c.m. squared
