What is the volume of this container

D.  

Step-by-step explanation:

We have been given an image of a container and we are asked to find the volume of our given container.

To find the volume of our given container we will use volume of cuboid formula.

, where,

,

,

.

We can see that a smaller cuboid is inside the bigger cuboid, so volume of container will be equal to volume of bigger cuboid minus volume of smaller cuboid.

Therefore, the volume of our given container is 1875 cubic inches and option D is the correct choice.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
