Answer:
222.7 cm³ of paper to wrap this.
Step-by-step explanation:
The rectangular prism is SA=2(wl+hl+hw)
Where:
w=5 l=5 h=4
SA= 2((5*5)+(4*5)+(4*5))
SA=2(25+20+20)
SA=2(65)=130cm³
The square base pyramid is 

≈92.69578 cm³
Add the two together 130+92.70 =222.7 cm³
Answer:
a) 800 square yards
b) 7200 square feet
Step-by-step explanation:
a) 40*20= 800 square yards
b) Each yard is 3 feet.
(40*3)*(20*3)=120*60=7200 square feet
Answer:
Step-by-step explanation:
The equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.
<h3>
What are length and width?</h3>
Length is describing how long is the object. The width is defined as how wide is the object.
Given that the width of the window is 4.9 feet. The length is given as 0.6 feet less than 2.5 times its width.
The height of the window is given as,

The other height of the window is given as,

When equating both equations, we get,

Therefore, an equation which is used to determine x, the width of the window is,
. Option B shows the correct expression for width x of the window.
