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
257+259+261+263 = 1040
1200 packets of tea
Its because theres 1000 grams in 1kg so it would be 600000 grams and you would divided 600000 over 500 and get 1200
