Question

please someone my brainly friends solve this surface areas and volumes question
2 cubes of each volume 64 CM square are joined end-to-end find the surface area of resulting cube please explain this problem point to point.

Answer 1

Answer:

When to cubes join together they form a cuboid.

Therefore, The length of the resulting cuboid will be double the side of cube whereas, the height and width will remain same as of cube

Step-by-step explanation:

1. Vol. of cube=l^3

  64=l^3

  l=4cm

TSA of Cuboid =(2lw+2lh+2hw)

                        =(2(8)(4)+2(8)(4)=(2)(4)(4)

                        =64+64+32

                         =160cm^2
