Find the volume of a pyramid with a square base, where the side length of the base is
nlexa [21]

Answer:

336.8 cubic meter or 336.8m³

Step-by-step explanation:

In other to solve the above question we would be using the volume of a square based pyramid.

The formula for the volume of a square based pyramid is

1/3a²h

In the above question we are given the following values as:

Side length of the base = a = 11.1 m

Height of the pyramid = h = 8.2m

Volume of the square based pyramid = 1/3 × 11.1² × 8.2

= 336.774 cubic meter or 336.774 m³

Approximately to the nearest tenth = 336.8 cubic meter or 336.8m³

Mr. Suárez wants to paint his storage shed. He needs to calculate the lateral surface area of the shed so that he will know how
WINSTONCH [101]

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The picture is the complete question.

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

4vir4ik [10]
Hello,
A=(2.21082279...,3.996803798)
\left \{ {{h=-0.2d^2+2.25d} \atop {h=d/6+21.77/6}} \right. \\\\

\Rightarrow\ 1.2d^2-12.5d+21.77=0\\\\

\Rightarrow\ d=2.21082279..\ or\ d=8.20584..\\\\
