Question

I need help finding the area of this prism the piscture will be below in a reply, please help me

Answer 1

u meant surface area?
mmmm
area of front face(L*H) = 5*8=40
area of rare face=40 since its at the front and at the back i mean 2sides but the back side is kind of invisible
area of side face (W*H)=10*8 =80
area of top and bottom(L*W)=5*10=50
area of bottom is also 50 since top and bottom are equal

=40*2 + 80*2 + 50*2
=80+160+100
=340
