Weekly Quiz Competition

Question 1
1 / -0

A covered wooden box has the inner measures as 115 cm, 75 cm and 35 cm and the thickness of wood is 2.5 cm. Find the volume of the wood.

A
53,000 cm³

B
82,125 cm³

C
84,000 cm³

D
85,000 cm³

Solution

Thickness of the wood = 2.5 cm
Now, external dimensions of the wooden box are :
Length = 120 cm, width = 80 cm & height = 40 cm
Volume of wood = (120 × 80 × 40) - (115 × 75 × 35) = 82125 cm³
Question 2
1 / -0

Find the sum of two opposite sides of a parallelogram whose height is 25 cm and area is 15 m².

A
10000 cm

B
11500 cm

C
11800 cm

D
12000 cm

Solution

Height = 25 cm

Area of the parallelogram = 15 m² = 150000 cm²

Area of the parallelogram = Base × Height

150000 = Base × 25
Base = 6000 cm
Now, sum of parallel sides = 6000 + 6000 = 12000 cm
Question 3
1 / -0

Four ice cubes of sides 11 cm, 12 cm 13 cm and 14 cm are melted and then frozen together again to form one big ice cube. Find the side of the new ice cube formed.

A
17 cm

B
20 cm

C
40 cm

D
50 cm

Solution

Let the side of the new cube be S.
According to the question,
Total volume of all the cubes = Volume of the new cube

11³ + 12³ + 13³ + 14³= S³

1331 + 1728 + 2197 + 2744 = 8000 cm³ = S³

S = 20 cm
