Question

If two cubes of edge 5 cm each are joined end to end, Find the surface area of the
resulting cuboid.​

Answer 1

Answer:

Given

one cube = 5cm

so l length=5+5=10

b breadth =5

h height = 5

Now ,

total surface area of cuboid= 2(lb+bh+hl)

= 2(10*5+5*5+5*10)

= 2( 50 +25+50)

= 2(125)

= 250
