Step-by-step explanation:
The described building have three dimensions. So, the building is in the shape of a Cuboid.
The volume of a cuboid= length* width*height
Given:
Putting the values in the formula of volume of a cuboid
Volume of the building
cubic units
The volume of the building is
Ответ:
Volume of a sphere=(4/3)pi(r^3)
You need to find the r value to calculate surface area, so I'll solve for that first.
(4/3)pi(r^3)=2254pi
(4/3)(r^3)=2254
r^3=1690.5
r=(1690.5)^(1/3), around 11.9126m
Substitute this in to find surface area
A=4pi(r^2)=4pi(11.9126)^2
=1783.2818 m^2
