This is true for any cross section parallel to the faces of a rectangular prism. They are congruent to the two rectangular bases of the prism since they are formed by cross sections that are in planes parallel to the bases. Two rectangular cross sections for the rectangular prism are shown in green above. Any cross section that is parallel to a face of a rectangular prism has the shape of a rectangle or parallelogram and is congruent to the face. The opposite faces are parallel and congruent to each other. The 12 edges of a rectangular prism are in 3 groups of parallel lines. A rectangular prism has 12 edges and 8 vertices. Characteristics of a rectangular prismĪ rectangular prism is enclosed by six faces consisting of two rectangular bases and four lateral faces in the shape of a parallelogram. A box, an eraser, and an aquarium are all examples of real life objects that can be in the shape of a rectangular prism. Below are a few examples of rectangular prisms.Ī rectangular prism is a shape that is commonly seen in everyday life. The lateral faces of a rectangular prism are parallelograms. Lateral surface area of equilateral trian-gular prism = Base perimeter × Heightīase area of equilateral triangular prism = \(\frac \) = 53 timesĪ prism is made by cutting cardboard as shown in the figure.ī.Home / geometry / shape / rectangular prism Rectangular prismĪ rectangular prism is a prism with rectangular bases. What is its total surface area?īase perimeter of equilateral triangular prism = 12 cm The base of a prism is an equilateral triangle of perimeter 12 centimetres and its height is 5 centimetres. Volume of the solid cube when edges are 8 cmĪ water trough is in the shape of a prism has trapezoidal faces Question 1. Volume of the water at first = Base area × height Sum of the volume of the water at first time and volume of the solid cube immersed equally to the product of base area and height of water level now. When a solid cube is immersed into water, the volume of water is raised. If a solid cube of side 8 centimetres is immersed in it, by how much would the water level rise? A hollow prism of base a square of side 16 centimetres contains water 10 centimetres high. Volume of water = Volume of the hexagonal prism = Area of the hexagon × heightĪrea of the regular hexagon is equal to six times the area of equilateral triangle. It is given that the depth of the pit is 3 metre but the water level is only in 1 metre. A hexagonal hole of each side 2 metres is dug in the school ground to collect rainwater. Calculate its volume.īase perimeter of an equilateral triangle = 15 cm. The base of a prism is an equilateral triangle of perimeter 15 centimetres and its height is 5 centimetres. We have the formula to calculate the volume of a square prism, i.e. It is represented in the form of cubic units. The volume of a square prism is the number of units that are used to fill a cube.
