It has two wide windows. The length of the window is 2 m and the width is 1 m. Thus, the area of the window is 2 m².

B. These are blocks А, В and С Block A is 4 cm high, 8 cm wide and 11 cm long. Block В has a height of 4 cm, a width of 10 cm and a length of 18 cm. Block С has the following dimensions: it is 5 cm high, 15 cm wide and 20 cm long. So, the volumes of the blocks are different. Block В is larger than block A, but block С is the largest.

II. Translate the following text into Ukrainan paying attention to British units of length.

The test section is a metal cylinder 2 ft 6 in long, 6 in id and 6.25 in od. Both ends of the cylinder have glass plates 1/4 in thick. An admission port (впускний отвір) 2.7 in diametre is at each end of the cylinder.

1 in = 1 inch = 2.54 cm

1 ft = 1 foot = 12 inches = 0.3048 m

id = inner diametre – внутрішній діаметр

od = outer diametre – зовнішній діаметр
