What's the Volume of this??
mr_godi [17]

Answer:

V = 90 cm^3

Step-by-step explanation:

The volume is given by

V = Bh

where B is the area of the base and  h is the height

The base is the two sides that are identical, which is the triangle

B = 1/2 bh

   = 1/2 (4*3)

   = 1/2 (12)

   = 6

Substituting into the volume equation, where h = 15

V = 6*15

V = 90 cm^3

prisoha [69]

Answer: F=140

Step-by-step explanation:

720=(x-60)+(x-40)+(x-20)+130+120+110

720-130-120-110=3x-120

360=3x-120

360+120=3x

480=3x

480/3=x

160=x

F=160-20

Next problem

102+31+x=180

133+x=180

x=180-133

x=47
