We know that total surface area is the area of of the base + area of all the walls + area of the top
here we are working with a pyramid whose base is a square but the wall are four triangles
as triangles are connected on the top , there would be no top area ( as the top would be a point ( where all four triangles are being join )
so total area is = area of base + area of four walls ( triangles here )
Answer:
The surface area of the net shown is: 88
Step-by-step explanation:
Break up the different shapes in the net:
Let's take the big square first:
It has a side of 5in and a base of 4in.
We multiply both these values to get 20
Lets look at the small rectangular box now:
It has a side of 3in and a base of 4in.
We multiply both these values to get 12
There are two big squares so we add up their surface areas:
20 + 20
= 40
There are 4 small rectangular squares so we add up their surface areas:
12 + 12
+ 12
+ 12
= 48
Now we add up the big square and small rectangular squares values:
40 + 48
= 88
Therefore the answer is 88
