First, we find the area of the base. We will call this area B. B = 3 ( 2 ) = 6 cm2. The six square units of area are drawn on one of the bases in the diagram at the right. In the diagram at the right, each square unit of area on the base has now been used to draw a cubic unit of volume.
17 Σεπ 2020 · Find the surface area of a rectangular pyramid with a slant height of 10 yards, a base width (b) of 8 yards and a base length (h) of 12 yards. Solution. SA = B + 1 2sP = (bh) + 1 2s(2b + 2h) = (8)(12) + 1 2(10)(2(8) + 2(12)) = 96 + 1 2(10)(16 + 24) = 96 + 5(40) = 296 yards2.
Area of the base =. 16 pi square units. A cylinder has a volume of 175 cubic units and a height of 7 units. The diameter of the cylinder is: 10 units. Find the following measure for this figure. Lateral area =. 5√ (146) pi square units. Find the following measure for this figure.
Volume and surface area help us measure the size of 3D objects. We’ll start with the volume and surface area of rectangular prisms. From there, we’ll tackle trickier objects, such as cones and spheres.
1) How could you determine the surface area of a triangular prism? 2) Is painting your house a real world example of surface area or volume? 3) What shape is formed by folding the following nets?
Correct answer is: 6 units The area of a triangle is 1/2 base height. So, height of the triangle = (2 area)/base, i.e., (2 21 square units)/7 units = 6 units.
Answer. The height of the prism is 80 units. Explanation. 1 Calculate the area of the base using the formula for a square: Base Area = side^2. 2 Substitute the given value: Base Area = 6^2 = 36 square units. 3 Calculate the height using the formula: Volume = Base Area × Height. 4 Substitute the values: 2880 = 36 × Height.
