Answer:
Width = 20 cm.
Step-by-step explanation:
Given : A cuboid of volume 30, 000 cm³ with length 30 cm and height 500 mm.
To find : What is the missing width of the speaker below when its volume is 30,000 cm³ .
Solution : We have given that
Volume of cuboid = 30,000 cm³.
Length = 30 cm .
Height = 500 mm .
1 mm = [tex]\frac{1}{10}[/tex] cm.
500 mm = [tex]\frac{500}{10}[/tex] cm.
500 mm = 50 cm.
Then height = 50 cm .
Volume of cuboid = length * width * height .
Plugging the values of volume , length , height .
30,000 = 30 * width * 50 .
30,000 = 1500 * width .
On dividing both side by 1500 and switching the sides.
Width = [tex]\frac{30000}{1500}[/tex].
Width = 20 cm.
Therefore, Width = 20 cm.
