These types of problems are meant for 7th-9th grade as they are more challenging and may require the use of an equation.Įach worksheet is randomly generated and thus unique. Looking forward, students can then progress to additional surface area worksheets and other geometry worksheets, for example a simplifying expressions worksheet or simultaneous equations worksheet.įor more teaching and learning support on Geometry our GCSE maths lessons provide step by step support for all GCSE maths concepts.You can also make problems where the volume or surface area is given along with some dimensions, and the students need to calculate either the volume or the surface area of the prism. Surface area of 3D shapes is measured in square units such as cm^2 or mm^2. The depth of a prism can also be referred to as the length or the height of the prism depending on its orientation. The total surface area can be found by calculating the sum of the areas of the triangular faces, area of the base and area of the top faces. Note that each rectangular face may have a different area, depending on its side lengths. We can then find the lateral surface area (the area of the rectangular sides). The triangular ends are exactly the same (congruent) so their areas will be identical. Remember that to find the area of a triangle, we multiply the base of the triangle by the height of the triangle and divide by two. When finding the surface area of the triangular prism, we start by finding the area of the triangular faces. To find the total surface area of a triangular prism, we find the area of each face and add them together.Ī triangular prism has five faces. A triangular prism is a 3D shape with identical triangles at each end, connected by a number of rectangular faces (lateral faces). Surface area is a measure of the total area of all of the faces of a solid shape. Surface area of a triangular prism at a glance
