Total surface area-lateral surface area
= 2*(surface of top + surface of bottom)
40-26
2*(surface of top + surface of bottom)=14
surface of top (or bottom) = 14/2=7
= 2*(surface of top + surface of bottom)
40-26
2*(surface of top + surface of bottom)=14
surface of top (or bottom) = 14/2=7

T.S.A=2(lb+bh+lh)
lb+bh+lh= 40/2 [eq 1]
L.S.A= 2h(l+b)
26/2=lh+bh [eq 2]
from eq 1&2 we get,
lb+13=20
lb=7cm
lb+bh+lh= 40/2 [eq 1]
L.S.A= 2h(l+b)
26/2=lh+bh [eq 2]
from eq 1&2 we get,
lb+13=20
lb=7cm
