Question

IV.
Find the surface area of the cuboids in each of the
are
ids in each of the following cases.
b. Length = 23 cm, breadth = 17 cm, height 14 cm
a. Length = 8 cm, breadth = 1.5 cm, height
= 0.2 cm
height
b. LE
= 14 cm
d. Length = 4.8 m, breadth = 2.4 m, height
C. Length = 8 cm, breadth = 6 cm, height =
10 cm
height =
d. Length -*.
= 1.6 m​

Answer 1

bro the first case with length = 26 and breadth = 17 cm and 14 as height

2(lb+bh+lh)

2(26*17+17*14+26*14)

2(442+238+364)

2(1044)

2088sq.cm

bro in the second case we take l = 8,b = 1.5 ,h

= 0.2

2(lb+bh+lh)

2(8*1.5+1.5*0.2+8*0.2)

2(12+0.3+1.6)

2(13.9)

27.8sq.cm

bro in the third case we take
