The height of the base and the perimeter length are respectively; 12 cm and 840 cm
How to find the volume of a Prism?
We are told that;
Volume of Triangular Prism = 1200 m³
Base length = 10 cm
Side length of triangle = 13
Length of box = 20
Now, formula for volume of a triangular prism is;
V = ¹/₄h√(-a⁴ + 2(ab)² + 2(ac)² - b⁴ + 2(bc)² - c⁴)
where;
a is side length of triangle
b is base side length
c is also side length of other triangle
h is length of box
Thus;
Using Pythagoras theorem, we can find the height of the base as;
D = √(13² - 5²)
D = √144
D = 12 cm
B) Formula for perimeter length of triangular prism is;
P = (S1 + S2 + S3)L + BH
P = (13 + 13 + 10)20 + 10(12)
P = 720 + 120
P = 840 cm
