Question

Surface area of this right prism

Answer 1

Explanation:

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

Answer 2

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

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

`\textbf{Area of Triangles :}`

• 
  `\sf{(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}`
