Answer 1

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

Let's calculate its surface area ~

`\sf SA = Area (2 × \triangle) + Area ( three \: \square)`

`\sf SA =(2 \cdot (1)/(2) \cdot8 \cdot6 ) + (7 \cdot10) + (7 \cdot 8) + (7 \cdot6)`

`\sf SA =(48 ) + (7 0) + (56) + (42)`

`\sf SA =216 \: m {}^(2)`
