MCQ: Volume, Surface Area & Solid Figures - 2 - SSC CGL MCQ

Side of the square = √32 = 4√2
Diagonal of the square = side√2 = 4√2 × √2 = 8 cm
Hence, Option B is correct.

Volume of a cuboid = lbh
So the answer = 20 × 4 × 8 = 640 cm³
Hence, Option C is correct.

Hence, Option D is correct.

Let the breadth of the rectangle = B
Length of the rectangle = L
L × B = 2 B × 2 B
L = 4B
L : B = 4 : 1
Hence, Option C is correct.

πr² = 154

r = 7
Perimeter = 2πr

Hence, Option B is correct.

πr² = 346.50

r² = 110.25
r = 10.50
So the answer = 2πr 

Hence, Option D is correct.

The volume of cube = side3
So the answer = 16 × 16 × 16 = 4,096 m³
Hence, Option D is correct.

Side of the square = √49 = 7 cm
So the answer = 7 × 4 = 28 cm
Hence, Option A is correct.

6l + 6b = 8l
6b = 2l
l : b = 3 : 1
Hence, Option B is correct.

Curved surface area = 4πr² 

Hence, Option A is correct.

Curved surface area = 2πrh

Plane surface area = 2 × πr² 

So the answer = 308 – 264 = 44 cm² 
Hence, Option B is correct.

Hence, Option C is correct.

Diameter of the circle = Side of the square = 14 meters
Radius of the circle = 7 meters
So the answer = πr² 

Hence, Option B is correct.

The area of an equilateral triangle

Hence, Option C is correct.

Hence, Option A is correct.
