Answer 1

(1) 4x6 =24 cm

(2) 8x4+6×4+5x4=32+24+20=76cm

Answer 2

LSA of cube = 4a²

= 4(4)²

= 4 × 16

= 64

TSA of cube = 6a²

= 6(4)²

= 6 × 16

= 96

TSA of cuboid = 2(lb+bh+hl)

= 2 { (8×6) + (6×5) + (8×5)}

= 2 ( 48 + 30 + 40 )

= 2 × 118

= 236

LSA of cuboid = 2 ( l + b ) h

= 2 ( 8 + 6 ) × 5

= 2 × 14 × 5

= 140
