Q1 of 64 Page 77

Find the Lateral Surface Area (LSA), Total Surface Area (TSA) and volume of the cubes having their sides as

31 cm

Given:

side of cube (a) = 31cm


(a) LSA of cube = 4a2


= 4(31)2


⇒ LSA of cube = 3844cm2


(b) TSA of cube = 6a2


= 6(31)2


⇒ TSA of cube = 5766cm2


(c) Volume of cube = a3


= (31)3


⇒ Volume of cube = 29791cm3
