Question

Work out the surface area and volume of the following shape




Please tell the answer​

Answer 1

Step-by-step explanation:

For cube

volume V1 = 5^3 = 125

For cylinder

volume V2 = 3.14*20*(3.5)^2 = 22238

Total volume = V1+V2 = 22363 cm^3

Surface Area

For cylinder

A1 = 2pi*rh + pi r^2

= 2*3.14*3.5*20 + 3.14*(3.5)^2. = 439.6 + 38.5 = 478.1

For cube

A2 = 6*l^2 - pi*r^2

= 150 - 38.5 = 111.5

Total surface area = 478.1 + 111.5. = 589.6 cm^2
