Explanation:
L. S. A. OF CUBE = 4(SIDE)²
= 4×(10)²
= 100×4= 400CM²
L. S. A. OF CUBOID = 2×height(length + breadth)
= 2×8(10+12.5)
= 16(22.5)
360cm²
so cube has larger lateral suface area
similarly u please find out the total surface area
by applying following formulas
T. S. A OF cube = 6(a) ²
T. S. A OF CYLINDER = 2(lb+bh+hl)
