Question

four cubes of volume 125cm cube each are joined end to end in a row find the s.a and volume of the resulting cuboid

Answer 1

Dear student

Volume of each cube = 125 cm³

So, Edge of each cube = 5 cm

For new cuboid formed, l = 5+5+5+5 = 20 cm

b = 5 cm

h = 5 cm

Therefore, surface area of the resulting cuboid = 2 (lb + bh + lh)

= 2 (20 X 5 + 5 X 5 + 20 X 5) cm²

= 450 cm²
And volume of cuboid=l x b x h = 20 x 5 x 5 = 500cm³
