The monomial is a perfect cube is 
.
<h3>Perfect cubes;</h3>
Perfect cubes are the numbers that are the triple product of the same number.
We have to determine
Which monomial is a perfect cube?
A perfect cube monomial must have three identical roots, such that the product of the roots equals the perfect square monomial.
It must be possible for the coefficient of a perfect cube monomial to be written in the form n3, where n equals the cube root of the coefficient.
A perfect cube monomial must have exponents on the variables.
Then
The monomial is a perfect cube is;
![\rm= 343p^6q^{21}r^6\\\\= \sqrt[3]{ 343 }= 7](https://tex.z-dn.net/?f=%5Crm%3D%20343p%5E6q%5E%7B21%7Dr%5E6%5C%5C%5C%5C%3D%20%5Csqrt%5B3%5D%7B%20%20343%20%7D%3D%207)
Hence, the monomial is a perfect cube is .

Step-by-step explanation:
- right triangle is A right triangle or right-angled triangle is a triangle in which one angle is a right angle
- acute triangle is An acute triangle is a triangle with three acute angles. An obtuse triangle is a triangle with one obtuse angle and two acute angles
- obtuse triangle is An obtuse triangle is one that has an angle greater than 90°. Because all the angles in a triangle add up to 180°, the other two angles have to be acute (less than 90°). It's impossible for a triangle to have more than one obtuse angle.
1. Area of the right angled ∆ = 1/2 × base × height
height = 16m
base = √20² – 16²
= √400 –256
= √144
= 12 m
Area of the unshaded portion
= 1/2 × base × height
= 1/2 × 12 × 16
= 96m²
2. Area of the rectangle = 300ft × 150ft
= 45000sq. ft
Area of the shaded portion = 100² + (1/2×b×h)
= 10000 + (1/2×120×150)
= 10000 + 9000
= 19000 sq. ft
Area of the unshaded part of the rectangle
= (45000 – 19000)sq. ft
= 26000 sq. ft
