15 POINTS! Please explain. A right triangular prism has a height of 3 ft, a width of 4 ft, and a hypotenuse of 5 ft. The depth of the triangle is missing. If the surface area of the triangular prism is 192 square ft, find the depth of the triangular prism.

positive the answer is 60 

The formula of the Volume is followed by the model: V = Bh Where B is the area of the triangle, which is given - 192ft² and h is the height, between the two ends. V = ?  B = 192ft² h = 3ft Following the equation; V = 192 * 3 ∴ = 576ft³ I hope you followed through. Also on note, if you aren't given the S.A [surface area], you will be required to use the Area formula. A = 1/2×base×height. Lets say we didnt know the area, your working should look like this ; V = Bh V =?  B = 1/2bh h = 3ft Thus, V = 1/2(b)(h)(3) Substitute the figures into b and h....also, the brackets means multiply.  Hope this helped you :)
