Question

three cubes of 4cm are joined to formally a cuboid find the lateral surface area of the resulting cylinder​

Answer 1

Answer:

Approx. 151 sq.cm

Step-by-step explanation:

Lateral surface area of a cuboid= 2h(l+b)= 2x 4(4+4)= 64 sq.cm

Lateral surface area of cylinder= 2πrh= 2x πx (4/2)x (4+4+4)= 2π x 2x 12= 150.796 sq.cm
