The total weight being carried is
3545 +1758 +3697 = 9000 . . . . . pounds

Each ton is 2000 pounds, so together the trucks are carrying
(9000 lb) × (1 t)/(2000 lb) = 4.5 t

Altogether, the 3 trucks are carrying 4.5 tons of topsoil.

Further explanatio n

7 main quantities have been determined based on international standards, namely:

1. Length, meters (m) 2. Time, second (s) 3. Mass, kilograms (kg) 4. Temperature, kelvin (K) 5. Light intensity, candela (cd) 6. Electric current, amperage (A) 7. Amount of substance, mol (m)

Mass is one of the principal quantities, which is related to the matter in the object (how much matter is in an object)

The main mass unit consists of 7 units of other than other units of mass such as quintals, tons, pounds, ounces:

Kilogram, kg Hectogram, hg Decagram, dag gram, g Decigram, dg centigram, cg milligrams, mg

Each unit descends then multiplied by 10, and if one unit increases then divided by 10

Conversion of other mass units:

mg milligrams = 10⁻³ g kg kilograms = 10³ g µg micrograms (mcg) = 10⁻⁶ g Mg megagrams (tons) = 10 g ng nanograms = 10⁻⁹ g Gg gigagram = 10⁹ g g picogram = 10⁻¹² g

For US standart mass , the most common units are

Ounces Pounds Tons

The conversions between those units are :

1 pound = 16 ounces

1 ton = 2,200 pounds = 32,000 ounces

so :

1 pound = 0,000453592 ton

Three dump trucks are carrying topsoil

Truck A carries 3,545 lb, Truck 8 carries 1,758 lb, and Truck C carries 3,697 lb

Total mass from three dump trucks are :

= 3,545 + 1,758 + 3,697

= 9000 lb
