We have, straight line angle = 180˚ Therefore, 0.2 time a straight line angle =
The letter D has one horizontal line of symmetry.
A closed wooden box measures externally 20 cm long, 14 cm wide and 9 cm high. If the thickness of the wood is 1 cm. find the weight of the box If 1 cm3 of wood weighs 0.5 g.
Externally measurement of a wooden box is Length = 20 cm, breadth = 14 cm and height = 9 cm External volume of wooden box = Since, the wood is 1 cm thick. Therefore, Internally measurement of the box is Length = 20 cm – 2 cm = 18 cm, Breadth = 14 cm – 2 cm = 12 cm and Height = 9 cm – 2 cm = 7 cm Therefore, Internal volume of wooden box = Therefore, volume of wood = Since, the weight of 1 cm3 of wood the box is 0.5 g. Therefore, total weight of the box
What is the square root of28
The square root of =
Length of the field = 80 m Breadth of the field = 60 m Therefore, required ratio =
Total student in the class = 50 and girls =40% Then, boys = (100 – 40)% = 60% Therefore, number of the boys in the class
