Q: What are Mensuration Class 8 Case Study Questions MCQ & Solutions?

Mensuration Class 8 Case Study Questions MCQ & Solutions are CBSE-based application questions that include multiple-choice problems with clear, step-by-step explanations for students.

The school plans to upgrade the assembly area into a small auditorium for Grade 8 activities. The floor will be **rectangular** (length $28$ m, width $16$ m). At the center, there will be a **circular stage** (radius $3$ m). A **cylindrical pillar** (radius $2$ m, height $6$ m) will support the canopy. Near the entrance, a kiosk will have a **conical roof** (radius $3$ m, height $4$ m). For storage, there is a **cuboidal box** (length $5$ m, width $4$ m, height $3$ m). The principal needs the maths teacher to calculate different mensuration measures so the contractor can estimate materials and costs for flooring, painting, and installations.

1. What is the perimeter of the rectangular auditorium floor (l=28m, w=16m)?

84 m 88 m 92 m 96 m

Solution:
Perimeter of rectangle $P = 2(l + w) = 2(28 + 16) = 2 \times 44 = 88$ m.
Correct answer is option **(b)**.

2. What is the area of the circular stage (radius $r=3$m)?

$6\pi$ sq m $9\pi$ sq m $12\pi$ sq m $18\pi$ sq m

Solution:
Area of circle $A = \pi r^{2} = \pi \times 3^{2} = 9\pi$ sq m.
Correct answer is option **(b)**.

3. What is the volume of the cylindrical pillar (radius $r=2$m, height $h=6$m)?

$12\pi$ cubic m $18\pi$ cubic m $24\pi$ cubic m $36\pi$ cubic m

Solution:
Volume of cylinder $V = \pi r^{2}h = \pi \times 2^{2} \times 6 = \pi \times 4 \times 6 = 24\pi$ cubic m.
Correct answer is option **(c)**.

4. What is the lateral surface area of the conical roof (radius $r=3$m, height $h=4$m)?

$9\pi$ sq m $12\pi$ sq m $15\pi$ sq m $18\pi$ sq m

Solution:
First, find the slant height $l$: $l=\sqrt{r^{2}+h^{2}}=\sqrt{3^{2}+4^{2}}=\sqrt{9+16}=\sqrt{25}=5$ m.
Lateral surface area of cone $LSA = \pi r l = \pi \times 3 \times 5 = 15\pi$ sq m.
Correct answer is option **(c)**.

5. What is the total surface area (TSA) of the cuboidal storage box (l=5m, w=4m, h=3m)?

86 sq m 90 sq m 94 sq m 98 sq m

Solution:
TSA of cuboid $TSA = 2(lw + wh + lh)$
$TSA = 2((5 \times 4) + (4 \times 3) + (5 \times 3))$
$TSA = 2(20 + 12 + 15) = 2 \times 47 = 94$ sq m.
Correct answer is option **(c)**.
