About this resource
Here's a fun and engaging lesson that helps students apply the geometry skills they are learning in the classroom to a real world mathematical situation: painting a doghouse.
It is designed to address the Common Core State Standards 6.G.A.2 and 6.G.A.4: Finding volume and surface area and drawing nets.
Students will:
Determine how many faces there are on a compound three dimensional shape (including a rectangular prism & a triangular prism).
Sketch the faces/create a net on the grid provided (one face includes a fractional length of ½ inch).
Use a table to help calculate the surface area of all of the faces.
Calculate the volume of this compound shape using a table to organise the information.
Answer the provided discussion questions. These are provided to get students thinking about the concepts of geometry and include the questions:
Explain why you didn’t calculate the area of the base of the doghouse.
If each container of paint covers 200 inches², how many containers should you buy?
Why would it be useful to know the volume of the doghouse?
Students are also asked about the formulae for volume of a rectangular prism and triangular prism.
Grades to Use With: This lesson is designed to target Common Core State Standards for Year 7 geometry. It could also be used for enrichment in Year 6, review in 7th or 8th grades, or in a secondary school special education classroom.

Teaching tips & learning objectives
Learning objectives
Students calculate the surface area of a compound 3-D shape by finding and summing the area of each unique face.
Students calculate the volume of a rectangular prism and a triangular prism that together form one compound shape.
Students apply a surface-area calculation to a real-world purchasing decision (how many containers of paint to buy).
Students explain, in writing, which formula they used to calculate each volume and why one face of the shape is excluded from the paint calculation.
Teaching tips
Have students sketch the four unique faces on the grid before touching the calculation tables, since the hint in the file notes there are exactly four distinct face shapes to find.
Walk through the fractional edge length (one-half inch) as a class first, since it appears in the triangular roof section and could trip up students calculating area from the grid.
Use the coverage-rate question (200 square inches per paint container) as a checkpoint for whether students can move from a calculated total back to a real-world purchasing decision.
Skills covered
Surface area of compound 3-D shapes — students find and sum the area of each unique face of a combined rectangular-and-triangular prism.
Volume of rectangular and triangular prisms — students calculate and total the volume of each prism section separately.
Real-world measurement application — students convert a calculated surface area into a paint-container purchasing decision using a given coverage rate.
