If the width and height of a rectangular prism are each shrunk to one seventh of the original size but the length remains the sa me, what is the formula to find the modified surface area
2 answers:
SA=2(LW+LH+WH) if W turns to 1/7W and H turns to 1/7H SA=2(L(1/7)W+L(1/7)H+(1/7)W(1/7)H) SA=2((1/7)LW+(1/7)LH+(1/49)WH) SA=2(1/7)(LW+LH+(1/7)WH) SA=(2/7)(LW+LH+(1/7)WH)
Answer:
SA =
Step-by-step explanation:
The surface area of a rectangular prism is given by :
Where l stands for length
w stands for width
h stands for height
Given is - If the width and height of a rectangular prism are each shrunk to one seventh of the original size but the length remains the same.
So, length = l
width =
height =
The new surface area will be =
SA =
Simplifying this we get:
SA =
There are many other ways to write this but it has the same meaning, so, we can take this as the answer.
SA =

Answer:
d=483t
Step-by-step explanation:
If i recall correctly
distance = velocity * time
This means that
d=483t
