Answer:

Step-by-step explanation:
we are given the base area and the height of a solid figure
since the base area is not perfect square
we assure the solid figure to be a cuboid
remember that,

we are given l×w is 40 and h is 7
so substitute

simplify multiplication:

hence,
the volume of the figure is 280 in³

Step-by-step explanation:
The range is the set of values for y. Since y=|x|, y is always positive and increases without bound as x approaches +oo. Thus the range is:
y≥0 which can also be expressed as y=[0, +oo)
