VIKAS BHARATI PUBLIC SCHOOL CLASS - SUBJECT- MATHEMATICS WORKSHEET- —Short Typo • Find the volume of a cube of edge 7 Cm. -2. A wall of length 25 m, width 60 cm and 2 m is constructed by bricks, each of dimensions 20 cm by 12 cm by 8 cm. How many bricks will be needed ? S. A CNTin is tossed 150 times and head is obtained 71 timeg_ Now, if a coin ig tnssed at random, what ig the probability Of getting a tail ? Prove that diagonals Of a square equal _ A pa Of coi is LOSS e d I O times are Observed as , HT, TH , IT, HT, TH, HT, HH. Prepare a frequency table on the basis of numlYr of Heads and hence calculate the relative frequency and of chance of occurance. 6. In ABCD is a quadrilateral in which z Find the measure of the smaller q. Two adjacent sides Of a parallelogram are 4 cm and 6 cm respectively. 'Pie angle betwen them is 600. Construct the parallelogram. 8. In the parallelogram ABCD, AC and BD are its diagonals intérsecting at O. P is the mid-point of DO and Q is the mid-point of OB. pmve that APCQ is a parallelogram. _9.
