you need to find exposed surface area.
what do u mean
TA of longer piece = 2(lw) + 2(hw) + 2(lh) 2*1*1 +2*6*1 + 2*1*6 = 2 + 12 + 12 = 26 TA of shorter piece = 2(lw) + 2(hw) + 2(lh) = 2*1*1 + 2*3*1 + 2*1*3 = 14 Add the two surface areas together. 26 + 14 = 40 then u need to subtract the Subtract the area where the two pieces of wood are attached. 40 - (2*1*1) =
what do u do for 40 - (2*1*1) =
@israa88
40 - (2) = 38
do u get it @theofficialunkownname
