Answer: 160cm².
Step by step explanation:
Given,
Volume of both cubes = 64cm³
Volume of one cube =a³
⇒ 64 = a³
(4) = a³
⇒a=4
To find: We have to find the Surface area of resulting cuboids.
We know that, when two cubes are joined
they form cuboid:
Length of cuboid=4+4= 8cm
Breadth of cuboid= 4cm
Height of cuboid = 4cm
Surface area of cuboid = 2(lb+bh+lh)2(8×4+4×4+4×8)
= 2(32+16+32)
= 2(80)
= 160cm²
Therefore, Surface area of Cuboid is 160 cm².
