Question

Find the total surface area of the rectangular prism in the figure. A) 174 cm^ 2 B) 522c * m ^ 2; 348c * m ^ 2 D) 432c * m ^ 2

Answer 1

`\huge\textbf{Hey there!}`

`\huge\textbf{Better understanding of the lesson}`

`\text{Formula for finding the area of rectangular prism: \boxed{\mathsf{2(wl + hl + hw) = a}}}\\\text{Whereas, \bf l = \underline{length}, w = \underline{width}, h = \underline{height.}, and a = \underline{area}}`

`\huge\textbf{Now, let's solve for the given equation}`

`\mathsf{a = 2*(8*6 + 9*6 + 9*8)}`

`\mathsf{a = 2*(48 + 54 + 72)}`

`\mathsf{a = 2(48) + 2(54) + 2(72)}`

`\mathsf{a = 96 + 108 + 144}`

`\mathsf{a = 204 + 144}`

`\mathsf{a = 348}`

`\huge\textbf{Therefore, your answer is: \boxed{\mathsf{348\ cm^2}}}\huge\checkmark`
