Answer:
330cm
Step-by-step explanation:
The formula to find the surface area of a rectangular prism is 2(lh+hw+lw)
(lh) in this formula is length times height
(hw) is height times width
(lw) is length times width
To find the answer to this problem lets make the height 3/5cm the width 10cm and the length 15cm
so now you would do (15*3/5) which is 9. This solve (lh)
then you would find (3/5*10) which is 6. This solves (hw)
and lastly you would find (15*10) which is 150. This solves (lw)
Now that you now the value of each one of these you replace it in the equation as so: 2(9+6+150)
now you solve the brackets which leaves us with 2(165)
now you multiply 2 with 165
and the answer is 330cm
Surface area = 330cm

2(5m) + m
<u>Step 2: Simplify</u>
- Multiply: 10m + m
- Add: 11m
Answer:
m = √n/3 -k
Step-by-step explanation:
√n = 3(k + m)
=> √n/3 = k + m
∴ m = √n/3 -k
Hope this helps!!
One answer could be 2 as 2^2 is 4 and 2+2 also equals 4
