# Math in Construction

Christina Sng for Maths@Singapore

Today, I met a man in the construction sector and had a lovely chat with him. It reminded me how important this sector is in our world. After all, we all need a place to live in and it is the construction industry that builds it.

It got me wondering what kind of math one needs to build a house or building?

To plan their blueprints, architects use geometry, algebra, and trigonometry. They calculate the probability of problems that might occur. Ratio is utilized when building from the blueprints to ensure the proportions are correct. The Pythagorean theoreom ensures builders accurately measure right angles.

“Construction workers add, subtract, divide, multiply, and work with fractions. They measure the area, volume, length, and width. How much steel do they need for an office building? How much weight in books and furniture will the library floors need to bear? Even building a small single-family home calls for careful calculations of square footage, wall angles, roofs, and room sizes. How many square yards of carpet? How much water do you need to fill up a swimming pool?”

Math is critical in the planning, building, and assurance that our homes are safe to live in. There’s a reason we all study trig after all!
