Question

Find the surface area of this net

Answer 1

You always have to find the LSA (lateral surface area) first.

(which is the shape's area combined w/out the bases.)

rectangle A would be 60 and so would rectangle C

rectangle B would be 96

if u add them all together that would be 12.5

Now you have to find the TSA (total surface area).

(which is the TOTAL net combined w/ bases)

the bases would be 7.5

7.5 x 2 is 12.5

Add the LSA and the TSA

216+12.5=228.5

so the overall answer would be 228.5cm

i hope this helps!!
