Find the volume of the prism.

Prism

The volume of the prism is 210 cm³

Step-by-step explanation:

The given image is a rectangular prism whose every surface is a rectangle of same area or different areas.  It has  a length, breadth and height.  It is a three dimensional figure and has a volume. To measure the volume we need to know the values of three sides namely length, breadth and height. Volume of a Rectangular Prism V is defined as the product of its three sides.

V = l×b×h

where l is the length, b is the breadth and h is the height

Given l = 5 cm , b = 6 cm and h = 7cm

Substituting the values of l,b,h is above formula

V= 5 × 6 × 7 cm³

⇒ V = 210  cm³

The volume of the prism is 210 cm³

b) the dogs need to shift their focus to human scent.

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
