Q:

# Find the length of the longest pole that can be placed in a room 12 m long 8m broad and 9m high.

 A) 14m B) 15m C) 16m D) 17m

Explanation:

Length of longest pole = Length of the diagonal of the room

Q:

Q:

The areas of three consecutive faces of a cuboid are 12 cm², 20cm² and 15 cm², then the volume (in cm³) of the cuboid is

 A) 60 B) 55 C) 45 D) 40

Explanation:

From the given data,

let the length, breadth and height of the cuboid are m, n, r

m x n = 12

n x r = 20

r x m = 15

Hence, m x n x n x r x r x m = 12 x 20 x 15

mnr = sqrt of (12x20x15) = 60 cub.cm.

Q:

If the area of three Adjacent faces of a cuboidal box are 120 cm², 72 cm², and 60 cm² respectively, then the volume of the box is

 A) 640 cub.cm B) 720 cub.cm C) 860 cub.cm D) 945 cub.cm

Q:

Solve the triangle b=36 a=38 c=18 for perimeter of the triangle?

 A) 74 units B) 92 units C) 56 units D) 54 units

Explanation:

We know, the perimeter of a triangle = sum of all the sides of a triangle = a + b + c

Here given that sides a = 38, b= 36 and c = 18

Now, perimeter of the triangle = a + b + c = 38 + 36 + 18 = 92 units.

Q:

The circumference of a circular base of Cylinder is 44 cm and its hight is 15 cm. Then the volume of the cylinder is?

 A) 2759 cub. cm B) 2247 cub. cm C) 2614 cub. cm D) 2311 cub. cm

Explanation:

Given Circumference of a circular base of a cylinder = 44 cm

We know that Circumference of a circle =

Now given the height of a cylinder h = 15 cm

Q:

What is the Formula for Volume?

The formula to find the volume is given by just multiplying Length, Breadth and Height of that object.

Thus, V = L x B X H

Volume Formulae :

1. Volume of Cube of side 's' = s x s x s = $s3$  cubic units.

2. Volume of Cylinder$πR2h$ cubic units.

[Where is Radius and h is height]

Q:

A town has a population of 4000 requires 140 liters of water per head. It has a tank measuring 18m x 12m x 8m. The water of this tank will suffice for ____ days?

 A) 3 B) 4 C) 5 D) 2

Explanation:

Water required = 4000 x 140 = 560000 lit = 560 cu.m (1 cu.m = 1000 lit)

Volume of tank = 18 x 12 x 8 = 1728 cu.m

Water of this tank will suffice for = 1728/560 = 3 days.
