For volume you need 3 dimensions, i.e. a 3rd value, and more importantly, make sure the units are the same. multiply each of the 3 values together for a cuboid
Volume = 3*7*2 = 105 cubic cm
The volume of that triangle is 49 feet
7*3*10 = 210 cubic units
The volume of the prism is 196 units^3
Assuming it is spherical (since it has a specific radius) then Volume = (4/3)pi*radius^3, so V = (4/3)pi*7^3 = 1436.76 cu. in.
210 cm³
Density is equal to mass divided by volume. mass of loonie is 7 grams volume of loonie is .78cm^3 7÷.78 = 8.974358974358974 g/cm^3
Volume of Hemisphere = 2/3 * Pi * (radius)^3 Volume of Cone = 1/3 * Pi * (radius)^2 * height where Pi = 22/7 (approx)
The volume would be 1436.7550...cm^3 and so on.
1/3 * 22/7(Pie) *r square * height = Volume So r = Whole Under Root (Volume/height*7/22*3) :D Hope it helps
Volume = 1/3*7*5*6 = 70 cubic units
343, 7*7*7, 7^3, Pull up your computer's calculator program. Way easier. Its what I did. volume is height times width times length. 7 times 7 times 7.
