Question

two cubes each of side is 5 cm are joined end to end find the surface area of the resultant cuboid

Answer 1

If 2 cubes are joines end to end a new solid cuboid is formed,So-
Length = 2×5cm = 10cm
Breadth=1×5cm = 5 cm
Height =1×5cm = 5 cm
T.S.A. of Cuboid= 2 (lb+bh+lh)
2 (10×5+5×5+10×5)
2 (50+25+50)
2 (125)
250cm2

Answer 2

Answer:

If 2 cubes are joines end to end a new solid cuboid is formed,So-

Length = 2×5cm = 10cm

Breadth=1×5cm = 5 cm

Height =1×5cm = 5 cm

T.S.A. of Cuboid= 2 (lb+bh+lh)

2 (10×5+5×5+10×5)

2 (50+25+50)

2 (125)

250cm2
