Question

A square pyramid has a base length of 1.1 meters and a slant height of 2.4 meters. Calculate the surface area of the solid and answer to the hundredths place if necessary.​

Answer 1

Check the picture below.

so the area of the pyramid is really just the summed up area of the 1.1x1.1 square on the base and four triangles with a base of 1.1 and a height of 2.4.

`\stackrel{ \textit{\LARGE Areas} }{\stackrel{ square }{(1.1)(1.1)}~~ + ~~\stackrel{ \textit{four triangles} }{4\left[\cfrac{1}{2}(\underset{b}{1.1})(\underset{h}{2.4}) \right]}}\implies 1.21+ 5.28\implies \text{\LARGE 6.49}~m^2`
