Question

If you could please just give me the formula for this provlem then I could do the math part that would be awesome. just number 3 and supposed to find volume and surface area.

Answer 1

volume=area of the triangle*depth, SA=area of triangle *2+area of bottom rectangle + area of side rectangle

Explanation:

so for the volume, it’ll just be the area of the triangle on the front (A=base*height/2) times the depth (or thickness, in this case 8mi),

The surface area is the area of each shape that makes the 3D object. There’s two identical triangles, one rectangle on the bottom (whereA=length*width) and another rectangle at the side/back.
