Fill in the following blanks:
| Volume of cuboid | Length | Breadth | Height | |
|---|---|---|---|---|
| (i) | 90 cm3 | - | 5 cm | 3 cm |
| (ii) | - | 15 cm | 8 cm | 7 cm |
| (iii) | 62.5 m3 | 10 cm | 5 cm | - |
Answer:
Volume of cuboid = length x Breadth x Height
(i) 90 cm3 = length x 5 cm x 3 cm
Length = 90/(5 x 3) = 90/15 = 6 cm
(ii) Volume = 15 cm x 8 cm x 7 cm
= 840 cm3
(iii) 62.5 m3 = 10 m x 5 m x height
Height = 62.5/(10 x 5) = 1.25 m
| Volume of cuboid | Length | Breadth | Height | |
|---|---|---|---|---|
| (i) | 90 cm3 | 6 cm | 5 cm | 3 cm |
| (ii) | 840 cm3 | 15 cm | 8 cm | 7 cm |
| (iii) | 62.5 cm3 | 10 cm | 5 cm | 1.25 cm |
