Let’s learn how to determine the surface area of a cube. What is a Cube? The only regular hexahedron, a cube is a three-dimensional object with six equal-sized square surfaces or sides, 12 edges, and 8 vertices. Given that its square sides are equal, it follows that a cube’s length, width, and height are equal, too. Examples of cube-shaped objects …

Let’s learn how to find the surface area and volume of a rectangular prism. What is a Rectangular Prism? Prisms are three-dimensional objects with two equal bases or ends, flat surfaces or sides, and the same cross-section along its length. A cube is a prism, but unlike a cube that has 6 equal square faces, a rectangular prism has six …

Let’s learn how to determine the volume of a cone. What is a Cone?  A cone is a three-dimensional object that has a circular base; a vertex or top; a height which is the perpendicular distance from the vertex to the base; and a slant height which refers to the distance from the vertex to the side and down to …

Let’s learn how to determine the area of a rectangle. A rectangle is a four-sided shape with equal and parallel opposite sides. Remember that area refers to the total amount of space enclosed in a shape. The area is expressed in square units such as square meter (m2), square in (in2), or square kilometer (km2) To find the area of …

Let’s learn how to determine the surface area of a cylinder. What is a Cylinder? A cylinder is a tube-shaped object with two same-sized circular bases, parallel straight sides, and a circular or oval cross-section. Its height is the distance between the two bases, while the radius is the distance from the center of a base to any point on the …

Let’s learn how to determine the volume of a cylinder. What is a Cylinder? A cylinder is a tube-shaped object with two same-sized circular bases, parallel straight sides, and a circular or oval cross-section. Its height is the distance between the two bases, while the radius is the distance from the center of a base to any point on the same …

Let’s learn how to determine the volume of a sphere. What is a Sphere? A sphere is a perfectly symmetrical three-dimensional shape whose all surface points are equidistant from the center. The distance from the center to any point on the surface is called the radius. Twice the radius is the diameter or the line segment that passes through the center. …

Let’s learn how to determine the perimeter of a rectangle. What is a Rectangle? A rectangle is a four-sided flat shape with two pairs of parallel and congruent lines that form a right angle on each of the four sides. A rectangle is also called a parallelogram – a quadrilateral whose opposite sides are equal and parallel. By this definition, …

Let’s learn how to determine the area of a circle. A circle is a shape containing a set of points that are equidistant from a given point. The point is called the center, and the distance from the center to any point in the circle is called the radius.  Twice the length of the radius is called the diameter – …
