Algebra 1a: CST Review – SURFACE AREA

Don’t forget SURFACE AREA of RECTILINEAR PRISMS and CYLINDERS!

For cubes and rectangles: AREA,  `A = l * w` and multiply by  `2`, the number of IDENTICAL FACES and then add them up.

For cylinders, find the lateral area (the side) and the lids:

AREA of LIDS: Area,  `A = π* r^2`, there are usually 2 of these

LATERAL AREA: The length * width (or height) of the ‘unrolled paper tube’. The length is the circumference of the circle and the width is the height of the tube. So …

LATERAL AREA: `A = h * (2π *r)`
