Answer:
Volume of a cuboid = (length × breadth × height) cubic units.
= (l × b × h) cubic units.
(Since area = ℓ × b)
Volume of a cuboid = area of one surface × height cubic units
Let us look at the given cuboid.
The length of the cuboid = 5 cm
The breadth of the cuboid = 3 cm
The height of cuboid (thickness) = 2 cm
The number of 1 cm cubes in the given cuboid = 30 cubes = 5 × 3 × 2
We find that volume of the given cuboid with length 5 cm, breadth 3 cm and height 2 cm is 30 cu cm.
If we are going to simplify the first number by dividing the given numerator by the denominator, we will get an answer of -5. This number and the second one are examples of rational number for they can be easily expressed as quotient of two number. However, the third one is irrational due to the repeating number 7 after the decimal point. Therefore, the answer is the third choice.
Answer: 22/13
Step-by-step explanation:
65e = 110
Divide 63 on both sides anyou get 22/13
In both cases, we can use a rule of three.
<h2>First part</h2>
Therefore, 4 students correspond to 20% of 20 students in total.
<h2>Second part</h2>
Therefore, 2 doctors correspond to 8% of 25 doctors in total.
