I need help with this.

So first, find the volume of both figures:

Solid one(to the left) is V=lwh

V=lwh

V=3.75x8x3.75

V=112.5

Now find the volume of the other figure (to the right):

V=lwh

V=8x3.75x8

V=240

Now, add the volumes together:

240+112.5=352.5

Hope this helps :3

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
