Question

what is the mass in gram of an aluminium block whose dimension are 2×3×4 inch and density is 2.7

Answer 1

d = m/v m=v×d. =24×2.756.7

Answer 2

Answer:

1061.88 g

Explanation:

1 inch = 2.54 cm

convert dimensions in inch to cm

length = 2 inch * 2.54 = 5.08 cm

breadth = 3 inch * 2.54 = 7.62 cm

height = 4 inch * 2.54 = 10.16 cm

volume of block = l*b*h = 5.08 cm * 7.62 cm * 10.16 cm = 393.29 cm³

Density = $\frac{mass}{volume}$

mass of aluminium block = Density * Volume

= 2.7 g/cm³ * 393.29 cm³ = 1061.88 g
