Find the surface area and show your work tell me what to multiply by like the equations

SA of a triangle: 1/2(base * height)

SA of a rectangle: length * width

SA of rectangle: 30 cm * 14 cm = 420 cm²

SA of top and bottom triangles: 2 * 1/2(30 cm * 20 cm) = 600 cm²

SA of side triangles: 2 * 1/2(14 cm * 24 cm) = 336 cm²

Add up all the SAs.

420 + 600 + 336 = 1,356 cm²

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
