Whats your question here?? if you are looking for volume of the the pyramidal tank, V=1/3 (Area of the base x Height)

first you need to get the area of the triangular base which has 3 ft on a side using formula A=1/2(BasexHeight) get the height using pythagorean theorem

c^2=a^2+b^2

3^2=1.5^2 + b^2 9+2.25=b^2 11.25=b^2 (get the square root of both sides) b=3.35ft

area of triangle A=1/2 (BxH) A= 1/2 (3ftx3.35ft) A=1/2 (10.05 sq. ft) A=5.025 sq ft

now the volume V=1/3 (Area of the base x Height) V=1/3 (5.025 sq ft x 7 ft) V=1/3 (35.175 cu. ft) V= 11.725 cu ft
