Question

Surface area.. please answer

Answer 1

160, I think. SA=2(lw+lh+wh).

Answer 2

`\boxed{ \mathfrak{\huge \: \underline{ \underline{A nswer} }: }}`

Given terms :

`\hookrightarrow \: length = 8 \: in`

`\hookrightarrow \: width = 2 \: in`

`\hookrightarrow \: height = 12 \: in`

we know,

`\large\boxed{ \mathrm{surface \: \: area \: (a) = 2(lw + wh + lh)}}`

`\hookrightarrow \mathrm{\: a = 2 * \bigg [(8 * 2) + (2 * 12) + (8 * 12) \biggr]}`

`\hookrightarrow a = 2 * \biggr[16 + 24 + 96 \biggr]`

`\hookrightarrow \: a = \bigg [\: 2 * 136\bigg ]`

`\hookrightarrow \large \boxed{ \mathrm{a = 272 \: \: in {}^(3) }}`
