Answer:

4480 ft^{3}

Step-by-step explanation:

Volume = (base)(height) / 3

Volume = ((32)(17.5))(24) / 3

Volume = (560)(8)

Volume = 4480

Therefor the volume of this pyramid is equal to 4480 ft^{3}

I am Lyosha [343]

Answer:

80 gifts

Step-by-step explanation:

Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?

Let the Total gifts that her sister has be represented by x

Hence:

15% of x = 12

15/100 × x = 12

15x /100 = 12

Cross Multiply

15x = 100 × 12

15x = 1200

x = 1200/15

x = 80 gifts

Hence, the total gifts her sister has is 80 gifts
