The expression that represents 5 less than d is d-5.
The volume of the given prism is 160 yards.
1.
Given,
The number is represented by d.
We need to find the expression that represents 5 less than d.
Let the number be d.
5 less = - 5
So 5 less than d is :
= d - 5
Because for example, we can say that 6 is 1 less than 7
i.e 7 - 1 = 6
Similarly, 5 less than d can be written as d - 5.
Thus, the expression that represents 5 less than d is d-5.
2.
The volume of a prism is given by :
V = Bh
Where B = base area and h = height.
Now,
We see that we have a rectangular base of the given prism.
So,
B = base area
= length x width
= 5 x 4
= 20 yards.
Now,
We have h = 8 yards.
The volume of the prism = Base area x height
= 20 x 8
= 160 yards.
Thus, the volume of the given prism is 160 yards.
