Question

2 cubes each of volume 64cm2 are joined end to end . find the total surface area of the resulting cubes​

Answer 1

Answer:

The side³ = 64 or 4 x 4x 4 cm i.e 4³, then each Cube is having side of 4 cms each. And a cube has 6 equal faces of the Same Dimentions, and Area of each side is, side² (cms square ).

Hence, The Total surface Areas of Two Cubes = 2. 6.s² or 2. 6 . 4.4 = 192 cm².

Now since Two Sides are Joined, the Area of the hidden sides is to be reduced from the total Area.

Therefore the Joint Area will be...

192 - 2.4² or

192 - 32 or

160 cm². Answer.
