2 The Learning focus of Practice 19 is on Measuring Problems 1, Solid figures 1,2,3,4,5,6 & 7 and Time Yourself Test Page 2 Measuring Problems 1 Question 1 Find the areas of A-E Formula for area L x W (length x width) Let’s complete the practice examples below. Practice Question: Find the area of a: 9cm x9cm =81cm2 Complete b and c in your notebooks. Using our example above, the area of shape a was 81cm2 , the perimeter of this shape would be 36cm. (9+9+9+9) Therefore, question 1a the solution would be 12cm x4cm=48cm2

4 Page 3 Solid figures 1 Solid figures are three-dimensional objects. ... Anything with those three dimensions (width, depth, and height) is a solid figure, and because we live in a three-dimensional world, these figures are all around us. Explanation 1: A cube is an example of a solid. Explanation 2: Here are some examples of solid figures constructed by cubes. Page 4 Solid Figures 2 Let’s look at further examples of solids. The word uniform means identical, or exactly the same, and a cross section is when you cut an object in half and reveal the shape inside. So, a uniform cross section is when you cut an object straight through, and the resulting shape inside matches the bases, or ends, of the shape exactly.
