Talking about using Nets to find Surface Area of

3-dimensional shapes!

Finding Volume is easy!V = lwhHow much stuff can we pack inside a box?

Remember the formulas for finding Area of rectangles, triangles, trapezoids, and parallelograms!Formula!Substitute!Solve!

Triangles are ½ of rectangles!

Remembering everything we learned is a challenge!But, With careful notes and practice we can do it!

STUFF TO REMEMBER!

Area of a Rectangle = (base)(height)= bh

Area of a triangle = ½ (base)(height) = ½ bh

Area of a parallelogram = (base)(height) = bh

Area of a trapezoid = ½ (height)(base + base) = ½ h(b + b)

Surface Area = find the area of each face of the shape and add the areas together!

Sometimes drawing a net helps to find the surface area!

Volume = (length)(height)(width) = lwh

Graphing points = (x,y), remember there are 4 quadrants!

Use the absolute value to find the distance between points. If the points are in different quadrants add! If the points are in the same quadrant subtract!
