<u>The Volume of a Rectangular Cuboid</u>
In a rectangular cuboid, all angles are right, and the opposite faces are equal.
The volume of a cuboid of dimensions a,b,c is:
V=a.b.c
The rectangular box is made of wood with externals dimensions of 25 cm by 20 cm by 15 cm.
The external volume of the box is:
The walls of the box are 0.5 thick each, this means that the internal dimensions are 1 cm less than the external dimensions, including the lid.
Thus the internal volume is:
The volume of the wood used is the difference between the external and the internal volumes:
The volume of the wood used is
Step-by-step explanation:
let total pizzas = y
so
32/100 x y = 64
y= 64× 100/32
= 200 pizzas
Answer:
The function is both injective and surjective.
Step-by-step explanation:
Given function,
We say a function is injective(one-one) when for every value of x we have a unique value of y.We say a function is surjective(onto) when the output y covers all the values of the co domain.
We know that in the graph of at no two points of x there can be a common y. So hence proved that is injective.
is also surjective because for x from - infinity to + infinity covers all the values in its co domain hence it is also surjecctive function.
