Question

Two cubes each of edge 4.5dm are joined face to face .Calculate the surface area of the jointed cuboid.​

Answer 1

sides of newly formed cuboid are length(l)=9m

breadth(b)=4.5m

height(h)=4.5m

surface area =2h(l+b)

=2*4.5(9+4.5)

=9(13.5)

= 121.

thank you☺

Answer 2

$\huge\underline\mathfrak\purple{Bts}$

l=9

b=4.5

h=4.5

Surface are=2(l+b)h

2(9+4.5)4.5

2(13.5)4.5

121.5 sq
