Question

Find the total surface area of a rectangular box without lid if its length, breadth and
height are respectively 1.2 m, 80 cm and 40 cm.​

Answer 1

Answer:

Total surface area = 2(lb+bh+hl)

Step-by-step explanation:

length = 1.2m

breadth = 80m

Height = 40m.

T.S.A = 2(lb+bh+hl)

2(1.2*80+80*40+40*1.2)

2(96+3200+48)

2(3344)

T.S.A=6688
