Answer:
the volume of the triangular prism is 1,185.6  in³
Step-by-step explanation:
To find the volume of these triangular prism, we will, first, find the area of the triangle then multiply by the length
Area of triangle =  × b×h
 × b×h
From the diagram ,the height of the triangle  is given to be 10.4 in and the base is given to be 12 in.
We will now proceed to insert the values into the formula;
                  Area of triangle  =  × b×h
 × b×h
                                               =  × 12×10.4
 × 12×10.4
                                               
                                                 =  × 124.8
 × 124.8
                                                  =62.4
Area of triangle is 62.4 in²
From the diagram is given to be 19 in
Volume of triangular prism = area of triangular prism × l
                                               =62.4 in²   ×    19 in
                                               =1,185.6  in³
Therefore the volume of the triangular prism is 1,185.6  in³

Answer:
A=27 cm^2
B=24 cm^2
C=26 cm^2
D=28 cm^2
Step-by-step explanation:
Break each problem down into individual shapes.
For instance, A can be split into a 3 by 3 square and a 6 by 3 square.
       Get the area by multiplying the length & height: A = L * H
For the triangles the area is the same equation divided by 2 A=LH/2
Shapes with unclear dimensions like C can be skipped and have their area revealed through process of elimination.
