There is a margin of 16px applied to the figure. You have the option to adjust this margin if you prefer:
.container3 {
width: 1000px;
height: 600px;
box-sizing: border-box;
border: 1px dashed black;
}
.container3 figure {
display: inline-block;
box-sizing: border-box;
margin: 0;
}
<div class="container3">
<figure>
<img class="image" height="200px" width="300px" src="/images/img-berryblitz.jpg" alt="berry blitz">
<figcaption>

</figcaption>
</figure>
<figure>
<img class="image" height="200px" width="300px" src="/images/img-spiced-rum.jpg" alt="spiced rum">

<img class="image" height="200px" width="300px" src="/images/img-donut.jpg" alt="donut">

</div>
If you wish to evenly distribute the available space between the images, you can utilize flexbox and apply justify-content: space-between:
.container3 {
display: flex;
justify-content: space-between;
width: 1000px;
height: 600px;
box-sizing: border-box;
border: 1px dashed black;
}
.container3 figure {
display: inline-block;
box-sizing: border-box;
margin: 0;
}
<div class="container3">
<figure>
<img class="image" height="200px" width="300px" src="/images/img-berryblitz.jpg" alt="berry blitz">
