Dimensions in the page of a product

Hi,
Thanks for getting in touch with us!
This is not related to WCFM and fully controlled by WooCommerce. Though I have write a snippet for you which can help you achieving your purpose –

add_filter('woocommerce_display_product_attributes', function( $product_attributes, $product ) {
    if(isset($product_attributes['dimensions'])) {
        $dimension = $product->get_dimensions( false );
        $formatted_dimension = array();
        if(!empty($dimension['height']))$formatted_dimension['height'] = "H. " . format_dimension_item($dimension['height']);
        if(!empty($dimension['length']))$formatted_dimension['length'] = "L. " . format_dimension_item($dimension['length']);
        if(!empty($dimension['width']))$formatted_dimension['width'] = "W. " . format_dimension_item($dimension['width']);
        $product_attributes['dimensions']['value'] = implode( ' × ', array_filter($formatted_dimension) );
    }
    return $product_attributes;
}, 10, 2);

function format_dimension_item($d) {
    return wc_format_localized_decimal($d) . " " . get_option( 'woocommerce_dimension_unit' );
}

Add this code to your child theme’s functions.php
In case you do not have child theme then add code using this plugin – https://wordpress.org/plugins/code-snippets/
Let me know how it goes.
