Answer:
<h2>231cm²</h2>
Step-by-step explanation:
First, let's find the surface area of both the triangles
5x3=15
So, the surface area of the triangles is 15 sq.cm
Now, let's find the surface area of the base (large rectangle in the middle)
12x8=?
10x8=80
2x8=16
80+16=96
12x8=96
So, the surface area of the base, is 96sq.cm
Now, let's find the surface area of both of the side rectangles
12x5=60
60x2=120
So, the surface area of the two side rectangles is 120sq.cm
Now, let's find the total surface area by adding all of our answers.
120+96=216
216+15=231
<h2>
So hence, the surface area of this net is 231cm²</h2>
Answer:
A, 1:2 ratio
Explanation:
Since 1 is <em>half</em> of 2, and the problem states that RSTUV is <em>half</em> of JKLMN, A is the correct ratio.
Do 5 divided by 6 to get your answer
Answer:
the answer is 1
Step-by-step explanation:
2^(3/2) - 7 + /-4/
2^(3/2) - 7 + 4
2^(3/2) - 7 + 2^2
2^(3/2) + 2^2 - 7
laws of indices reversed
2^(3/2×2) - 7
2^3 - 7
8 - 7
<u>1</u>
