There are two terms because
One is __x the other is the constant
9x + 4 - 3x + 7
6x + 4 - 7
6x - 3 has two terms
The surface area of a hexagonal prism willl be 251.13844 cm².
<h3>What is the surface area?</h3>
The total land area of all the faces of a three-dimensional object is its surface area. When we wish to wrap something in real life, we employ the notion of surface areas of distinct things.
A=6ah+3√3a²
A=6×4×7+3√3×4²
A≈251.13844
Hence the surface area of a hexagonal prism willl be 251.13844 cm².
