Answer 1

252 m²

Explanation:

Surface area of rectangular prism:

l - length = 6 m

w - width = 3 m

h - height = 12 m

Substitute l, w and h in the below mentioned formula:

`\boxed{\text{\bf Surface area of rectangular prism = 2*(lw + wh + hl)}}`

`\sf = 2*(6*3 + 3*12 + 12*6)\\\\= 2 * (18 + 36 + 72)\\\\= 2* 126\\\\= 252 \ m^2`
