Question

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

Answer 1

Answer:

C.  S.A. = 340.8 $cm^{2}$

Step-by-step 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 $cm^{2}$
