Question

Two identical cubes each of tsa of 6 sq cm and joined end to end which of the following is the tsa of the cuboid formed

Answer 1

Step-by-step explanation:

TSA of cube =6 cm²

6a² =6cm²

a²=1

a=1

then,

two cubes are joined

So,

length of cuboid= 2

breadth=1

heigth=2

TSA of cuboid =2(lb+bh+hl)

=2(2×1+1×1+2×1)

=2(2+1+2)

=2×5

=10cm²
