spayn [35]
Let the hypotenuse be x then,
Using the pythagoras theorm,
10^2 + 24^2 = x^2 (alt^2 + base^2 = hypo^2)
100 + 576 = x^2
676 = x^2
Therefore x= square root of 676 = 26

What is the volume of the square pyramid round to the nearest thenth 10 cm 12 cm 12 cm
oksano4ka [1.4K]

Answer:

Step-by-step explanation:

The formula for determining the volume of a square based pyramid is expressed as

Volume = 1/3 × base area × height

Since the base is a square, all sides would be equal. The formula for finding the area of a square would be applied. From the information given, length of each side of the square is 12 cm. Therefore,

Base area = 12² = 144 cm²

Height = 10 cm

Therefore,

Volume = 1/3 × 144 × 10 = 480 cm³
