A shipping carton is in the shape of a triangular prism. How many cubic inches
of space are in the carton?

O15 in
O70 in
O80 in
O90 in
O100 in

90 inches

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a rectangular prism =area of the base x length  

Area of the base is the area of a triangle:

Area of a triangle = base x height x 1/2

Replacing with the values given:

A = 4 x 3 x 1/2 = 6 in2

Back on the volume formula:

V = A x h = 6 x 15 = 90 cubic inches  

Feel free to ask for more if needed or if you did not understand something.

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
