Answer:
1.85
Step-by-step explanation:
So, s (sketchbook) is a+1.90.
8a+ 3(a+1.90)=26.05
8a+3a+5.7=26.05
11a=20.35
a=1.85
Check:
8x1.85=14.8
s=11.25
Answer:

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
