Question

25. Two cubes each of edge 8cm are joined end to end. Find the surface area of the resulting cuboid.​

Answer 1

Answer:

Given,

Side of cube=8cm

Now.

If the cubes are put side by side

Length=16 cm

Breadth=8cm

So,

Surface area of the resting cuboid=length x breadth

       =16 x 8

       =128cm²

Step-by-step explanation:

Answer 2

Answer:

Step-by-step explanation:

If two cube are join then it form cubiod

L=8+8 =16cm , b=8cm, h=8cm

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

=2(16*8 +8*8+16*8)

= 2( 128 +64 +128)

= 2(320)

= 640cm2
