One cubic centimetre of aluminum weigh 2.70g. What is the weight in grams of a rectangular block of aluminum 50cm long,7.5cm broad and 12cm high
volume of your block = (50)(7.5)(12) cm^3
multiply that by 2.7 g
To calculate the weight of the rectangular block of aluminum, we need to find its volume, and then multiply it by the weight of one cubic centimeter of aluminum.
The volume of a rectangular block can be calculated by multiplying its length, breadth, and height.
Volume = length x breadth x height
Given:
Length = 50 cm
Breadth = 7.5 cm
Height = 12 cm
Volume = 50 cm x 7.5 cm x 12 cm
Volume = 4500 cm³
The weight of one cubic centimeter of aluminum is given as 2.70 grams.
Now, we can calculate the weight of the rectangular block:
Weight = Volume x Weight of aluminum per cubic centimeter
Weight = 4500 cm³ x 2.70 g/cm³
Weight = 12150 grams
Therefore, the weight of the rectangular block of aluminum is 12150 grams.
To find the weight of a rectangular block of aluminum, we need to calculate its volume and then multiply it by the density of aluminum.
First, let's find the volume of the block:
Volume = length x width x height
Volume = 50 cm x 7.5 cm x 12 cm
Next, multiply the volume by the density of aluminum:
Weight = Volume x Density
Weight = (50 cm x 7.5 cm x 12 cm) x 2.70 g/cm³
Now, let's calculate the weight:
Weight = 4500 cm³ x 2.70 g/cm³
Multiplying these values together:
Weight = 12,150 g
Therefore, the weight of the rectangular block of aluminum is 12,150 grams.
