#3 Add all the areas for total surface area.Hint: Multiply area of triangle by 4to get total area of all triangles. #1 Determine area of each triangle: #2 Determine area of the square base: base times height, then divide by two length times width Square base Triangle base Triangle height Surface area is the measurement of a solid shape. Surface area is not the measurement of a solid shape. Surface area is the measurement of the exposed surfaceof a solid shape. Surface area is the measurement of the inside surfaceof a solid shape.
