Me with these questions! can i have fully shown work for both, and the directions say to find the surface area of the piracies .

Start with the bottom, which is a 5 by 5 square, and you get 25ft^2 or square feet
Then the four sides. The area for a triangle is 1/2 base*height.
5*8 is 40/2=20
There are four of these sides so 20*4=80. 
Add this to the bottom and you get 80+25=105 square units

Omg that is a big question and weird words and i’m only 5
