Answer:
Step-by-step explanation:
LSA of a cuboid: 2 ( l + b ) h
TSA of a cuboid: 2 ( lb + bh + hl )
LSA = 2 ( 4 + 8 ) × 9
= 2 × 12 × 9 = 216cm^2
TSA = 2 ( 4 × 8 + 8 × 9 + 9 × 4 )
= 2 × ( 32 + 72 + 36 )
= 2 × 140
= 280cm^2

Answer:HEY BUDDY! THESE ARE STRAIGHT ANSWERS WITH THESE FORMULAS....
Lateral surface area-2h[ L+B]
TOTAL SURFACE AREA-2[LB+BH+HL]
Step-by-step explanation:
LATERAL SURFACE AREA=2*9[4+8]
=18*12
=216
TOTAL SURFACE AREA=2[32+72+36]
=2[140]
=280
