Answer:
volume ≈ 75.8 ft³(nearest tenth of a cubic foot)
Explanation:
A square base pyramid has the base of the pyramid as a square. The lateral faces are triangular. The volume of a square base pyramid is the product of the base area and the height of the pyramid divided by 3. Mathematically, it is expressed below
The volume of a square base pyramid = 1/3Bh
where
B = base area
h = height of pyramid
B = 19. 6 ft²
h = 11. 6 ft
volume = 1/3 × B × h
volume = 1/3 × 19.6 × 11.6
volume = 227.36/3
volume = 75.7866666667
volume ≈ 75.8 ft³(nearest tenth of a cubic foot)

Answer:
Explanation:
Given data:
exhaust velocity = 2.455 km/s
specific impulse = 294 second
Ve = effective exhaust velocity
Isp specific impulse
g_o = standard gravity
from above equation we have
![\frac{mo}{mi} = e^{\frac{\Delta v}{Ve} [tex]\frac{mo}{mi} = e^{\frac{2455}{2881.2}](https://tex.z-dn.net/?f=%5Cfrac%7Bmo%7D%7Bmi%7D%20%3D%20e%5E%7B%5Cfrac%7B%5CDelta%20v%7D%7BVe%7D%3C%2Fp%3E%3Cp%3E%20%5Btex%5D%5Cfrac%7Bmo%7D%7Bmi%7D%20%3D%20e%5E%7B%5Cfrac%7B2455%7D%7B2881.2%7D)
[ 2.455 km/s = 2455 m/s]
