Question

Use the net to determine the total surface area. Please help ASAP

Answer 1

C. S.A. = 340.8
`cm^(2)`

Explanation:

Area of rectangles = 6x 12 = 72
`cm^(2)`

all three have the same area - 72 x 3 = 216
`cm^(2)`

Area of triangle = 10.4 x 12 ÷ 2

Since there are 2 trignles - 10.4 x 12 = 124.8
`cm^(2)`

Add all sides up

S.A. = 216
`cm^(2)` + 124.8
`cm^(2)`

S.A. = 340.8
`cm^(2)`
