Volume is the measure of the amount of space inside of a solid figure,

cylinders

Perimeter

Composite

The distance around a two-dimensional shape.

Regular

surface area

prisms

the outside part or uppermost layer of something (The area of all sides of a shape.)

A composite shape is a figure that can be divided into more than one of the basic shapes. (a shape that has another shape attached to it)

A regular shape, also known as a regular polygon is a shape that has sides that are all equal

A cylinder is one of the most basic curvilinear geometric shapes, the surface formed by the points at a fixed distance from a given straight line, the axis of the cylinder.

prism

(V)=(1.3cm)X(6cm)X10cm)=78cm

(v)=(1/2 h)x (L)X(W)

a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.

To find surface area you have to find the area of each side and add them all together:)
