Is the last number together??
Answer:
see explanation
Step-by-step explanation:
(a)
The shaded figure is a trapezium with area (A)
A = 0.5 h(a + b)
where h is the perpendicular height and a, b the parallel sides, thus
A = 0.5 × 10 × (8 + 14) = 5 × 22 = 110 cm²
(b)
The volume (V) of the prism is calculated as
V = area of end face × depth
= 110 × 3 = 330 cm³

In order to divide a fraction by a whole number, you must make the whole number a fraction, by putting the number over one. In order to divide something by a fraction, you flip the divisor (3 or 3/1) to get the reciprocal (1/3) and multiply the two fractions together. Hope this helps! <span />
