Question

I need the surface area for this prism. If you could provide a formula too, that would be great!

Answer 1

136
`m^(2)`

Explanation:

Back of the shape area/ front of the shape area

A =
`(1)/(2)`
`(bh)`

A =
`(1)/(2)` (6 × 4)

A =
`(1)/(2)` (24) Divide 24 ÷ 2

A = 12

Bottom of the shape area

A = l · w

A = 7 · 6

A = 42

Left side of the shape area/right side of the shape area

A = l · w

A = 7 · 5

A = 35

---------------------------------------------------------------------------------

35 + 35 + 42 + 12 + 12 = 136
`m^(2)`

SA = 136
`m^(2)` Surface Area = 136
`m^(2)`
