Answer:
B. 1/392 cubic yard
Step-by-step explanation:
The volume is the product of base area and height:
V = Bh = (1/28 yd²)·(1/14 yd) = 1/(28·14) yd³ = 1/392 yd³
Answer:
B. 1/392 cubic yard
Step-by-step explanation:
Given,
The base area of the pillar, B = [tex]\frac{1}{28}[/tex] square yard ,
Its height, h = [tex]\frac{1}{14}[/tex] yd
Thus, the volume of the pillar would be,
[tex]V=B\times h[/tex]
[tex]=\frac{1}{28}\times \frac{1}{14}[/tex]
[tex]=\frac{1}{28\times 14}[/tex]
[tex]=\frac{1}{392}\text{ square yard}[/tex]
Since, the concrete he needs to cast the pillar = Volume of the pillar
= [tex]\frac{1}{392}\text{ square yard}[/tex]
Option 'B' is correct.
