Answer:
Devin will need 9 cubes of wax.
Step-by-step explanation:
To find the volume of the pyramid, you use (area of the base)* height of the pyramid divided by 3. You know the volume of a cube of wax is 32 cm^3. The volume of your pyramid is 270 cm^3. 270/32=8.4375.
Once you get 8.4375 cubes, you round to the next whole number, which is nine.
Answer:x=30*
Step-by-step explanation:
90*+30*=120*
*All triangles’ angles = 180*
180*-120*=60*
60*/2=30*
What way are you trying to solve
Answer:
New can holds
more than the old can
Step-by-step explanation:
Given: Diameter of the can is 6 cm and height is 12 cm such that volume of can is 
Dimensions of the can are increased by a multiple of 1.10
To find: Difference between the volume of new can and volume of old can
Solution:
Volume of can (v) = 
Let r, h denote radius and height of the can.
Let R, H denotes radius and height of the new can.
r = diameter/2 = 
h = 12 cm
R = 
H = 
New volume (V) = 
So,
