A bar of lead is in the shape of a rectangular prism 2 cm by 3 cm

svetoff [14.1K]

Answer:

Step-by-step explanation:

V = L * W * H

L = 4

W = 3

H = 2

V = 4 * 3 * 2

V = 24

Density = mass / Volume

density = 11.34

volume = 24

mass = ?

11.34 = mass / 24 Multiply both sides by 24

11.34 * 24 = 24 * mass /24

mass = 272.16 grams

Answer:

286 mm²

Step-by-step explanation:

A trapezium is given with ,

Parallel sides = 24mm , 28 mm
Height = 11mm .

The area is given by :-

$:\implies$ Area = 1/2 ( b₁ + b ₂) × h

$:\implies$ Area = 1/2 ( 24 + 28)×11 mm²

$:\implies$ Area = 1/2 × 52× 11mm²

$:\implies$ Area = 286 mm²

<h3>Hence the area of the trapezium is 286 mm².</h3>
