Answer:
Volume of a cuboid = length × breadth × height
Given :: Volume = 189 cm³ , Length = 7 cm , Height = 4.5 cm
Asked::: Breadth =??
Vol. = lbh = 189 = 7× 4.5× b
189 = 7 × 9/2 × b
== 21 = 7 × 1/2 × b
== 3 = 1/2 × b
==b = 3× 2 = 6
=== b = 6cm
Volume of cuboidal wooden block=189 cm^3
Length of cuboidal wooden block=7 cm
Breadth of cuboidal wooden block=?
Height of cuboidal wooden block=4.5 cm
Volume of cuboidal wooden
block=Length×Breadth×Height
189=7×Breadth×4.5
Breadth=×4.5
Breadth=6 cm
