Short Answer Type Questions
Wheather it may be lattice for dice or (RBSESolutions.com) not give reason for your answer too.
No. Because pair of opposite faces are having 1 and 4 whose total is 5 ≠ 7 and other faces (RBSESolutions.com) are having 3 and 6 and whose total is 9 which is not equal to 7. Right lattice is as follows.
Here to make a cube uncompleted lattice is given completed it with at least two methods. Remember this that a cube has 6 faces (Draw two separate figures) To (RBSESolutions.com) make the work easy you can use square paper.
Lattice of cube :
The cuboid figure is given. See (RBSESolutions.com) the figure and draw a dotted line figure.
Dotted line figure is given below :
Long Answer Type Questions
Dice are such cubes which has dots (RBSESolutions.com) marked on each face, Sum of dots on each opposite face of a dice is always 7.
Hence to make dice (cubes) two lattice are given. Every number written in each square shows the number of dots of that box.
By remembering that the sum of dots of (RBSESolutions.com) opposite faces are always 7 fill the number in blank spaces.
Number is blank spaces are as follows :
2 cm length cubes are kept near by a cuboid is made. Try to make a transversal figure of this and tell what is the length, breadth and height may be.
As shown in figure let us kept two cubes (RBSESolutions.com) together whose sides are 2 cm. Then its length will increase (2 + 2) cm means 4 cm. But breadth will not increase it will remain 2 cm and height will also be 2 cm.
For every solid three various shape are given. 1, 2, and 3 are given (RBSESolutions.com) then identify the top, front and side elevation.
(i) (1) → Top, (2)→ Side (3) → Front
(ii) (1) → Top, (2)→ Side (3) → Front
(iii) (1)→ Side, (2)→ Front (3) → Top
(iv) (1)→ Side, (2)→ Top (3) → Front
