The document discusses finding the surface area of a tent designed for scouts. It describes the tent as being in the shape of a square pyramid with a height of 2 meters and base of 4 meters. It asks what formula would be used to calculate the surface area and solve the problem of determining how much fabric is needed to construct the tent.
5. Are you a scout member

6. Mark Vincent works in a company that makes tents. His boss
assigned him to design tents for scouters. He needs to keep
them light. To decide what fabrics are acceptable to
scouters, he needs to know the amount of fabric it takes to
construct a square pyramid tent whose height is 2 meters and
a base of 4 meter. How much fabric is required to construct
this tent?
Let us read about a story problem regarding a scout member.
What is asked in the problem?
What are the given facts?
What formula shall we use to solve
the problem?

8. The tent is in the form of a pyramid.
How many faces does the tent have?
What is the shape at the bottom of the tent?
How about the shape of the sides of the tent?
Let us solve the problem.
To find how much fabric is
required to construct the tent,
let us separate the different
shapes that makes up the tent.

This is how their tent looks like. Their tent is in the form of a pyramid. The base
The bottom surface on which the figure rests is called the base. Some figures have a base at each end, like a prism, which has two bases. Apart from the base or bases, the remaining faces surrounding the figure are the lateral faces. These lateral surfaces make up the sides of a three-dimensional figure.
