Answer:
area of trapezium: -
formula...
½(sum of parallel sides)×height=area
=>240=½(12+x)×12
=>240=(12+x)×6
=>240=60+6x
=>6x=240-60
=>6x=180
=>x=180/6
=>x=30cm
therefore, the value of x is 30 cm.

Cavalieri's principle states that volume formulas for pyramids and cones will also apply to both right and oblique solids, a<span>s long as the "matching" cross section areas are equal.
So we can use the formula V=bh regardless of the resulting shape.
V = bh = </span>π(15 m)²(12 m) = 2700π m³ ≈ 8482.3 m³
