Answer»

Given,

Length = 20 cm, breadth = 15 cm, height = 8 cm

Total surface area= 2(lb+bh+lh) =2[(20×15)+(20×8)+(15×8)]=2[300+160+120]= 1160cm2

Lateral surface area= [2(l+b)×h] = 2(20+15)×8 = 560 cm2 (ANS)

TSA = 1160 SQ.CMLSA = 560 SQ.CM

TSA=1160SQMLSA=560SQ.CM

1160cm2560cm2 is the best answer
