Question

find the total surface area and lateral surface area of cube of side 18 cm​

Answer 1

T.S.A=6asq

=6×18sq

=6×324

=1944cmsq

C.S.A=4asq

=4×18sq

=4×324

=1296cmsq

Answer 2

Total surface area of cube

$6(side) { }^{2} \\ 6(18) {}^{2} \\ 6(324) \\ 1944cm {}^{2}$

lateral surface area of cube

$4(edge) { }^{2} \\ 4(18) {}^{2} \\ 4(324) \\ 1296cm {}^{2}$
