Answer:
1.25cm
Step-by-step explanation:
<em>Complete question:</em>
The prism has a volume of 35 cm cubed workout h, the height of the triangular cross section
<em>length=7cm</em>
<em>width = 4cm</em>
<em></em>
The volume of the prism is expressed as;
Volume = Base Area * Height
Given
Volume of the prism = 35cm^3
Base Area = length * width
Base Area = 7cm * 4cm
Base Area = 28cm^2
Substitute the given values into the formula
35 = 28* Height
Cross multiply
35 = 28 * Height
35 = 28 Height
Height = 35/28
Height = 1.25cm
Hence the height of the triangular cross section is 1.25cm
