The base units of the SI system (Systeme International, as it's known in French) are kilograms (mass), meters (length/distance), and seconds (time).
Because of this, the SI system is sometimes called the kg-m-s system. There are many others, but their use has become deprecated over the past 100 years or so.
Believe it or not, all other SI units are based on these three units. Even seemingly unrelated units like Volts.
Good luck.
Derived units are units formed by combining base units through mathematical operations, such as area (square meters). Supplementary units are units used alongside base units to form the complete set of units in a system, such as the radian for angles in the International System of Units.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
Derived units are made from a combination of base units through multiplication or division. These combinations can involve different base units raised to various powers, which allows for the creation of new units of measurement for quantities such as area, volume, velocity, and acceleration.
The base unit of resistance is measured in ohms.
The fundamental units are based on specific standards for each unit. Derived units result from manipulating the fundamental units. For example, the SI unit for distance or length is the meter, and the SI unit for time is the second. If you divide meters by seconds, you get m/s, a derived unit for speed or velocity.
the 3 main base units would be, > ?
The volume of a cylinder 8 units tall and with 3 for the radius of the base is: 226.2 cubic units.
The area of a triangle is (1/2)(base)(height), or (1/2)bh. In this case, the base is 3 units and the height is 4 units, so the area is (1/2)(4)(3), which is 6 units squared.

37 * * * * * No. Total surface area = Lateral area + 2*base area = 10*3 + 2*7 = 30 + 14 = 44 sq units.
The other base measurement which is 18 units in length. Check: Area = 1/2*(18+3)*10 = 105 square units
Lateral area = 10*3 = 30 sq units Total area = Lateral area + 2*Base area [top and bottom] = 30+2*7 = 44 sq units
80 cubic unitsUsing the formula bh/3, the base is found to be 30 square units and the height is given as 8 square units. Plugged into the equation, 30*8/3 equals 80 cubic units.
To find the volume of a prism, you multiply the area of the base by the height. If the base dimensions are 5 and 3 (assuming these are the length and width), the area of the base is 5 × 3 = 15 square units. Then, multiply the base area by the height of the prism (10): 15 × 10 = 150 cubic units. Therefore, the volume of the prism is 150 cubic units.
