Identifying 3-D Solids :Identifying 3-D Solids Prisms: three-dimensional figures named for the shape of their base. Rectangular prism: bases are rectangles Triangular prism: bases are triangles Cylinders: three-dimensional figures that have circles for bases
Prisms :Prisms Name the prisms found in my house Rectangular Prisms Triangular
Prism rectangle square triangle
Cylinders :Cylinders Name the cylinders found in my house circle
What is volume? :What is volume? The amount of space inside a figure
Measured in cubic units …. unit³
Finding Volume :Finding Volume Formula V = Bh
Volume = big B x height the volume equals the area of the base times The height of the figure length width height base
Find the volume of the rectangular prisms :Find the volume of the rectangular prisms V = B x h
V = (area of base) x (height)
V = (lw) x (h)
V = (5x5) x (5)
V = 125 in³ 5 in 5 in 5 in The length of the spaghetti box is 1 inch, the width is 8 inches and the height is 4 inches.
V = Bh (lw x h)
V = (1 x 8) x 4
V = 32 in³
Find the volume of the triangular prism :Find the volume of the triangular prism 7cm 8 cm 10 cm V = Bh
V = (area of base ) x (height of prism)
Note – the bases are the top and bottom of the piece of cake
V = (1/2 bh) x h
V = (1/2 x 7 x 10) x 8
V = 280 cm³
Find volume of cylinders :Find volume of cylinders 4 in 6 in V = Bh
V = (area of circle) x (height of cylinder)
V = (∏ r²) x h
V = (3.14 x 2²) x 6
V = 75.36 in³
Find the volume :Find the volume The radius of the candle is 3.5 cm and the height is 9 cm.
V = Bh
V = (∏r²) x h
V = (3.14 x 3.5²) x 9
V = 346.185 cm³
Not done yet !! :Not done yet !! 10 ft 6 ft 7 ft Rectangular Prism
V = Bh
V = (6 x 7) x 10
V = 420 ft³
