Answer:
Option (1)
Step-by-step explanation:
To calculate the volume of the given pyramid,
Formula to be used,
Volume =
Area of the triangular base =
=
= 67.5 cm²
Now volume of the pyramid =
= 720 cm³
Therefore, Option (1) will be the correct option.
Answer:
The value of x is 2.11
Step-by-step explanation:
area of a triangle=95m^2
perpendicular(p)=3x
base(b)=3x
now,
area of right angled triangle=1/2*b*p
or,95=1/2*3x*3x
or,95*2=9x
or,190=9x
or,190/9=x
x=21.11
