Free Perimeter, Area and Volume 02 Practice Test - 5th Grade
Question 1
If the dimensions of a box is 6 m×4 m×5 m, then its volume is:
120 m3
158 m3
132 m3
128 m3
SOLUTION
Solution : A
Volume of the box =Length×Breadth×Height
=6 m×4 m×5 m
=120 m3
Therefore, volume of the box will be 120 m3.
Question 2
If the perimeter of a square is 16 cm, then its area is:
4 cm2
8 cm2
16 cm2
32 cm2
SOLUTION
Solution : C
Given: Perimeter = 16 cm
Perimter of a square = 4 × Side
⇒ 16 cm = 4 × Side
⇒ Side =164=4 cm
Area of a square = Side × Side
⇒ Area of the square =4 cm×4 cm=16 cm2
Question 3
Find the perimeter of the triangle given below.
150 cm
90.8 cm
170 cm
90.08 cm
SOLUTION
Solution : C
We know that 1 m = 100 cm
⇒ 0. 8 m = 0.8 × 100 cm = 80 cm
Perimeter = Sum of all sides = AB + BC +AC
⇒ Perimeter = 50 cm + 40 cm + 80 cm = 170 cm
Question 4
If the area of a rectangle is 63 cm2 and its breadth is 7 cm, then the length of the rectangle is:
6 cm
7 cm
8 cm
9 cm
SOLUTION
Solution : D
Given:
Breadth of a rectangle = 7 cm
Area of the rectangle = 63 cm2Area of rectangle = Length × Breadth
⇒ Length = AreaBreadth
⇒ Length = 63 cm27 cm=9 cm
Question 5
If the dimensions of a brick is 20 cm×10 cm×5 cm, then the volume of two such bricks will be ____ cm3.
1000
2000
3000
4000
SOLUTION
Solution : B
Given: Dimensions of a brick is 20 cm×10 cm×5 cm.
Volume of the brick =length×breadth×height=20 cm×10 cm×5 cm=1000 cm3
Volume of two bricks =2×1000 cm3=2000 cm3
Question 6
A rectangle is formed by keeping two squares next to each other. The length of the sides of each square is 10 cm.
What is the area of the rectangle formed by these two squares?
SOLUTION
Solution : B
Given: The length of the sides of each square is 10 cm.
For the rectangle formed:
Length = 10 cm + 10 cm = 20 cm
Breadth = 10 cm
Area of the rectangle = Length × Breadth = 20cm×10 cm=200 cm2
Question 7
If the perimeter of a square is 40 cm, then find the length of its side.
SOLUTION
Solution : B
Given: Perimeter of the square = 40 cm
Perimeter of a square = 4×Side
⇒ 4×Side=40 cm
⇒ Side=10 cm
∴ If the perimeter of a square is 40 cm, then the length of its side will be 10 cm.
Question 8
If the volume of a cube is 1000 cm3, then the length of its side will be:
SOLUTION
Solution : C
Given: Volume of the cube: 1000 cm3
Volume of a cube = Side3
⇒ Side3=1000 cm3
⇒ Side=10 cm
Therefore, the length of the side will be 10 cm.
Question 9
Length and breadth of a rectangle are 10 cm and 5 cm. Find its area.
SOLUTION
Solution : D
Given: Length of the rectangle = 10 cm
Breadth of the rectangle = 5 cm
Area of a rectangle = Length × Breadth
= 10 cm×5 cm
= 50 cm2
Therefore, area of the given rectangle is 50 cm2.
Question 10
The side of a cube is 4 cm long. Find its volume.
SOLUTION
Solution : D
Given: Length of each side = 4 cm
Volume of a cube = Side3
= (4 cm)3
= 64 cm3
Therefore, volume of the given cube is 64 cm3.
