Hernan cuts a board that is 7/10 of a meter long After the cut the board is 3/10 of a meter long how long is the piece that he c
ut of
2 answers:
Given that original lenght of the board before cut meter
Lenght of the board that is left after cutting from the original piece by Hernan meter
Now we have to find the lenght of the piece which is cut.
To find that we just need to subtract smaller piece from larger piece
Required Length meter
Required Length meter
Required Lengthmeter
reduce the fraction
Required Length meter
Hence final answer is meter.

The surface area of the triangular prism is: B. 72 sq. ft
<h3>Surface Area of a Triangular Prism</h3>- The surface area of a triangular prism is given by the formula: SA = bh + (s1+s2+s3)H
- Where, b is the base, h is the height, and s1+s2+s3 is the perimeter of the triangular base, H is the length of the prism.
Thus, given the triangular prism as shown in the diagram attached below, we have the following:
b = 4 ft
h = 3 ft
H = 5 ft
s1 + s2 + s3 = 3 + 4 + 5 = 12 ft
- Plug in the values
Surface area = 4×3 + (12)5 = 12 + 60 = 72
Therefore, the surface area of the triangular prism is: B. 72 sq. ft
