Step-by-step explanation:

I will answer this question with the attached square pyramid

From the attached pyramid, we have:

So, the base area is:

The dimension of each of the 4 triangles is:

So, the area of 4 triangles is:

So, the surface area is:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
