Question

three equal cubes each side 2cm are placed adjacently un a row. Find TSA of the cuboid formed​

Answer 1

Step-by-step explanation:

dimensions of cuboid -

l = 3 × 2 = 6 cm

b = 2 cm

h = 2 cm

TSA of cuboid = 2( 6 × 2 + 2 × 2 + 2 × 6) cm²

= 2 ( 12 + 4 + 12) cm²

= 2 ( 28) cm²

= 56 cm²
