Help me in this question ​

Answer 1

1.63 cm

Explanation:

Volume of water in Tank A

• 7 x 7 x 7
• 343 cm³

Volume of Tank B

• 15 x 14 x 10
• 210 x 10
• 2100 cm³

Finding Height

• Volume of water of Tank A filled in Tank B / Base Area of Tank B
• 343 / 210
• 1.63 cm

Answer 2

1.63 cm (nearest hundredth)

Explanation:

Formulae

Volume of a cuboid = base width × base length × height

Area of a rectangle = width × length

Tank A

Given:

• base width = 7 cm
• base length = 7 cm
• height = 7 cm

⇒ Volume of Tank A = 7 × 7 × 7 = 343 cm³

Tank B

⇒ Base area of Tank B = 14 × 15 = 210 cm²

Solution

Height = volume of Tank A ÷ base area of Tank B

= 343 ÷ 210

= 49/30 cm

= 1.63 cm (nearest hundredth)
