Surface Areas and Volumes Practice 2: Volumes and Hollow Solids

Section A: Skill Practice

Question 1mcq

A cylindrical tank is open at the top. To find metal sheet needed, which surface area is counted?

A.Only circumference

B.Curved surface area plus one circular base

C.Curved surface area plus two bases

D.Only volume

Question 2mcq

Two cubes are glued face-to-face. Which surfaces should not be counted in exposed surface area?

A.The two glued internal faces

B.All outer faces

C.Only top faces

D.No faces are hidden

Question 3mcq

Which measurement is needed for the curved surface area of a cone?

A.Only diameter

B.Only volume

C.Only diagonal of base

D.Slant height

Question 4mcq

A student uses

\pi r^2h

to find the amount of paint for the outside of a cylinder. What is wrong?

A.Paint needs litres only

B.Radius should never be used

\pi r^2h

is volume, not surface area

D.It is the correct formula for paint

Question 5mcq

D.Break the solid into known parts and decide whether surface area or volume is needed.

Question 8mcq

Which approach best matches the skill: subtract volumes for hollow or removed parts?

A.Count hidden shared surfaces as exposed

B.Ignore units and shape features

C.Break the solid into known parts and decide whether surface area or volume is needed.
