Take 3 dice of 1cm. Keep them adjacent to each other in a row. Find the surface area and volume of all three dice separately and that of the new shape formed after joining them
Answers
Answer:
The surface area of all the cubes = 6 cm²
The volume of all the cubes = 3 cm³
The volume of the cuboid = 3 cm³
Step-by-step explanation:
Given:
3 ludo dice of sides 1 cm each
To find out:
The surface area and volume of each cubes and the volume of cuboid formed by joining the 3 dices edge to edge
Solution:
We know that, if a cube has its side as a
Then its volume is given by a^3a
3
And its surface area is given by 6a^26a
2
Thus,
The volume of each of the 3 cubes = 1^31
3
cm³
= =1=1 cm³
The surface area of each of the 3 cubes
= 6\times 1^26×1
2
= 6 cm²
The cuboid formed by joining the cubes edge to edge will have its
Length L = 1 + 1 + 1 = 3 cm
Breadth B = 1 cm
Height H = 1 cm
Therefore, the volume of the cuboid
= L × B × H
= 3 × 1 × 1
= 3 cm³
