Top answer

Answer 2

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)
